—A base for the dash, the doghouse and the dinette

In the Bounder brochure, “holder” appears twice. One of them is the toilet roll.

Name: The Motorhome Cup Holder
Brand: Steadi Labs

That is the 2018 Fleetwood Bounder Class A gas brochure — about eighteen thousand characters of specification. The word occurs once for “Driver/Passenger Cup Holders” and once for the paper holder in the bathroom. You can check it yourself; the PDF is public.

It is not an oversight peculiar to Fleetwood. Read on for the other four coaches we counted.

A can standing in a white Steadi on a wooden table in a warmly lit interior. — On the table, wherever the table is. Twelve colours in all.

—We counted, so you do not have to

Five coaches, five sets of manufacturer literature.

These are word counts from the manufacturers’ own published brochures and spec sheets, read on 3 September 2026. Nothing here is our estimate.

Winnebago View, 2019

21 pages

The words “cup holder”, “drink holder” and “beverage” do not appear anywhere in the brochure — not in the cab section, not in the interior section.

Winnebago Aspect, 2017

20 pages

No cup holder is named anywhere in the coach. The only beverage-related item in the whole document is an optional “dash and beverage tray appliqué”.

Winnebago Journey 34N

whole spec list

“Cup holders” appears exactly once in the entire standard-features list for this Class A diesel, and it sits in the cab section.

nothing

A 5.2-inch moulded base, 3.6 ounces. It goes on the dash, the engine cover, the dinette or a theatre seat’s side table, and it comes back off.

—Where they do appear, and where they do not

The cockpit gets them. The lounge gets a side table.

Thor lists drink holders as cockpit equipment
On the Four Winds 22Z and the Windsport 36H alike, “Drink Holders” sits in the section headed Automotive & Cockpit. That is the front of the coach.
The Windsport’s theatre seats get a table instead
Specified as “Leatherette ‘Theater Seats’ with Integrated Footrests & Side Tables in Arms”. A side table is a flat surface, which is a different thing from a well — and it is the surface this product is for.
To be fair to Class C: the 22Z does have interior ones
Two of them, named in the Interior section — the cabover sleeping bunk and the dinette booth. If you have a 22Z, you have more than most coaches on this list.
And the makers sell the cab as living space
Winnebago’s own words: the cab seats “swivel and recline making them ideal for long trips or lounging at the campsite”, and elsewhere the driver’s seat swivels “to become an integral part of the living space”. Which is exactly why a sloped dash and an engine cover end up being where people set drinks down.

A hand sliding an aluminium can down into the fins of a Steadi. — The whole installation. No drilling, no clamp, no vacuum cup.

—Does it actually work

It wobbles. Then it settles.

Somebody swivels the captain’s chair, or drops onto the dinette bench, and the drink comes back level instead of going over. The base is 5.2 inches across and spreads the load rather than balancing on a point.

Filmed on a couch cushion — softer and less predictable than a dinette top or a doghouse, which is the point of showing it there.

A full can standing in a white Steadi on a cushion. — Real footage, one take, no cuts.

—How it holds

Width, and nothing else.

The base

5.2 inches across and fixed. It moves the edge the drink would have to tip over much further out, so the whole thing has to lean much further before it goes.

The fins

Six of them, holding the bottom inch. Cans and bottles slide on from the top; tumblers and glasses drop in. Drink and base then rock as one piece.

The surface

A wide foot spreads the weight across a dinette top, a side table or an engine cover instead of pressing into it at a point. It marks nothing and lifts away clean.

—The object

One piece of rubber. Nothing drilled.

No AMPS pattern to bolt down, no rail to clamp, no vacuum cup and no screws. It stands on the surface and it lifts off. Before you pull out, it goes in a drawer with everything else.

Several sizes of can standing in Steadis side by side, from a slim can to a tallboy. — Slim can to tallboy. Bases between two and three inches all seat.

—What seats and what does not

Bases between two and three inches. Measure the bottom, not the rim.

A standard 12 oz can is 2.6 inches across the bottom. A Stanley Quencher 40 oz is 3.1 and seats snug. A mug with a handle does not seat at all — the handle lands exactly where the fins grip, and that is a straight no.

One thing we could not find for you: nobody publishes a dash or engine-cover dimension for a Class A or Class C coach. We went looking through chassis and coach literature and there is no such figure. So this page does not tell you how much room you have; it tells you the base is 5.2 inches and leaves the measuring to you.

Search by container

Every width below comes from a published specification, not from us. Where a spec is uncertain, the answer says so.

Container

Or the width across the bottom

Width in inches

A width across the bottom of the cup, in inches.

Without a tape measure

A standard sticky note is three inches square. A cup standing on one with its base inside the paper will seat.

Anything that overhangs, or anything borderline — hello@steadilabs.com reaches a person, and the answer will be honest either way, including a no.

—Where they end up

The doghouse, the dash, the dinette, the side table.

The engine cover between the captain’s chairs, which is the flattest large surface in the front of a Class A. The dash where it is level. The dinette booth. The side tables built into theatre-seat arms, which are surfaces rather than wells. Outside, the folding table and the cooler lid.

Twelve colours, and the picker assigns one per unit, which with company aboard is mostly about telling whose drink is whose.

—What the aisle costs

Every mounted answer wants a hole, a rail or a glass-smooth panel.

Prices were looked up on 3 September 2026, not estimated. Every figure is the seller’s own.

The product	Price	What it asks of the coach
Optronics foldable cup holder	$9.31	“Screw mount onto panel — hardware not included.” Six mounting holes, no fasteners supplied. Opening adjusts about 2.5″ to 3.75″.
Optronics drop-in holder, two tier	$11.15	Nothing to mount — it “drops into one of your vehicle’s drink holders.” It presupposes the thing you came here looking for.
JR Products adjustable cup holder	$13.57	“Screw-mounts easily to any flush surface.” Takes containers to 44 fl oz, folds to 4″ square.
RAM Level Cup with Tough-Claw mount	$40.49	No drilling, but it needs “round, square, odd shaped rails and bars” to grip. A Class A dash top offers no rail.
RAM Level Cup with drill-down base	$47.49	A 2.5″ AMPS base drilled and bolted into the coach.
SeaSucker one-cup holder, horizontal	$65.00	A 4.5″ vacuum mount. SeaSucker says it mounts “to any horizontal surface”, and their own FAQ adds the condition: “as long as it’s non-porous. Wood by its very nature is porous.”
The Motorhome Cup Holder	$14.95 · four for $39.95, $9.99 each	Nothing. It stands on the surface and moves to whichever seat somebody is in.

Two of those are cheaper than this one, and the $9.31 Optronics is a perfectly good product. It needs six screw holes in a panel and fasteners you supply yourself. If you know exactly where the drink should live for the next ten years, that is the better buy and you should take it.

The RAM and SeaSucker mounts are proper engineering and they are built for vehicles in motion, which this is not. Different job, different price.

—From people who bought one

None of these is from a motorhome.

We are not going to imply otherwise. They are here because they describe the surfaces this page is about — a dash, a table, a cushioned top that is not quite level. Verbatim, unedited, not filtered by rating.

A dim living room at night: a glass of dark cola sits in a sage-green STEADI base on a fabric-topped ottoman while a calico cat walks across the same ottoman; a TV plays in the background — Photograph sent in by Dixie with this review.

★★★★★

I have a tendency to spill my drinks and have two cats. This is one of the best things I’ve ever impulse bought. It works. It actually works. It’s a heavy, wide enough base that it is actually stable. My “spot” in the living room is near a somewhat-cushioned fabric ottoman, which is where I usually put my drinks. It’s totally stable on this cushioned surface. It fits cans, bottlers, glasses. It doesn’t get bent out of shape. It’s exactly what I needed.

Love ‘em. One next to TV, the other in the car.

Steadi works very well in stabilizing my drinks on soft surfaces, like the couch or by the chair I use as a nightstand.

Marie Adams · July 2026

Love having my drink next to me on the screened porch but was always nervous it would spill... not anymore! Great product and great company.

—The limits, in one place

What it does not do.

It is not for use while the coach is moving.
Nothing loose is. It has no clamp and no fastener, so it belongs to a coach that is parked and levelled. If you want a drink secured while you are driving, the RAM and SeaSucker mounts above are built for exactly that and this is not.
It does not attach to anything.
No AMPS base, no rail collar, no vacuum cup, no adhesive, and there is no accessory that would add one.
A sloped dash is still a sloped dash.
A wide foot makes a knock much less likely on a level surface. It does not make a slope level, and on a steeply raked dash a drink will still want to travel.
A handled mug does not seat.
The handle lands exactly where the fins grip. That includes two-handled mugs, and a stemmed glass is a straight no as well.
It is not spill-proof — nothing is.
It resists tipping by widening the footprint the drink has to lean past. A hard enough knock moves anything.

—If it turns out to be the wrong thing

Scott Rodriguez made the first one after a full drink went over on a soft cushion with three kids under three in the house. It was built for spills, not for coaches.

Nobody with a Class A asked for this page. It exists because a wide base does the same thing on an engine cover as it does on a couch, and because five brochures in a row turned out to have almost nothing to say about where a drink goes.

We make one thing and we make all of it here — the moulds, the material, the colour runs, everything within about three and a half miles of the shop.

—Questions

Straight answers.

Can I use it while I’m driving?

No. It has no fastener of any kind, so it is for a coach that is parked and levelled. For a drink secured while the coach is moving, a RAM mount is the correct product and it is engineered for it.

Will it sit on the doghouse?

If the engine cover is flat and level where you want it, yes — that is usually the largest flat surface in the front of a Class A. If yours is domed or carpeted and sloped, it will sit but it will not be doing its best work.

How much room does it need?

5.2 inches across. We would rather tell you that than guess at your dash: no manufacturer publishes a dash or engine-cover dimension, and we looked.

Will it hold a 40 oz Stanley?

Yes. The Quencher H2.0 40 oz is about 3.1 inches at the base, inside the range the fins flex to. Snug rather than drop-in — it seats with a push.

Does it work on the theatre-seat side tables?

Yes, and that is one of its better spots. Thor specifies those arms with side tables rather than wells, which means a flat surface with nothing on it.

Will it mark the dash or the dinette?

It marks nothing and lifts clean. There is no adhesive, no suction and no hardware.

Where does it go when we travel?

A drawer. It is 2.8 inches tall and about 3.6 ounces, and they nest.

Why does this site only sell one thing?

Because it is one thing. It is a Steadi, made by Steadi Labs in Orange, California, and checkout finishes at steadilabs.com where the company lives.

—Still deciding

$14.95 for a piece of rubber.

It is, and the Optronics is $9.31. You are paying about six dollars to avoid six screw holes in a panel and to have the thing work at the dinette, in the lounge and outside as well.

My coach does have cup holders.

Some do — the Four Winds 22Z has them at the cabover bunk and the dinette, and it is better provisioned than most coaches we counted. The question is whether they are where you actually sit at seven in the evening.

I’d rather mount something properly.

Then mount something properly. RAM makes very good hardware and it is designed for a vehicle in motion, which is a thing this genuinely cannot do.

Will it survive being stored all winter?

Shore 85A TPU, no moving parts, no hinge, no metal to corrode. Long-term UV exposure is not something we have tested, so we do not make a claim about it.

In the Bounder brochure, “holder” appears twice. One of them is the toilet roll.

Five coaches, five sets of manufacturer literature.
