That RV is very cool! You are right in that you can blow through a lot of gasoline before you have a loss.
Drive the snot out of it and enjoy it!

UltraVan .. first I ever heard of/seen it that I recall. that's knowledge gap is like "waving a red flag" in front of a "nerd" like me ... 
Its got a following too... source: Ultra Van Brochures - Ultra Van Motor Coach Club

FYI ... these guys advertise it, other sources do NOT contradict it that I can see, that they have the best selling model of Class A RV's ever.

Asde: What is Class A? source: What's the Difference Between Class A, B & C Motorhomes?
For quality and luxury, the Class A motorhome is the way to go. Plenty of storage space and a roomy interior are what defines the Class A motorhome. 2-4 people can sleep in the motorhome as there is a bedroom located in the back and couches that fold down into beds in the living room area.
I dont' have the energy/interest to really dig into it, but I would have bet "Winnebago" has sold the most.
Again, makes me no real difference. Nice stuff being made now.. but gimme that "old iron" from vintage OE's or bus conversions (pre 1970's models, or whenever fiberglass started to dominate the OE Class A market).
Anyway, thirteen folks making Class A rigs now .. many around for long time:

Class A Motorhome
Class A motorhomes are built using a very strong, heavy-duty frame. These frames are built on either a commercial bus chassis, a commercial truck chassis, or a motor vehicle chassis. The 18-wheeler trucks use a similar build. The big, 22.5 inch wheels support the heavy load of the Class A motorhome. With 8-10 MPG, the Class A motorhome has the worst fuel economy. There are usually a minimum of two slide-outs.For quality and luxury, the Class A motorhome is the way to go.

It's Not Going to Shift Itself
Fleetwood has kept the Bounder name going for many years so the claim as the best selling model may well be true. Many other manufacturers have kept the "model" but changed the name. Also with the consolidation in the industry the model name may have remained the same, but is now made by a different parent company so that claim couldn't be made. The Bounder has been only made by Fleetwood. The model name of the coach I had is still around, but is now a Thor product instead of Damon.

Here's another rare one for ya's.... The English Commer Van. I noticed these when seeing footage of the Rolling Stones being transported to Court back in the 60s for drug charges.

Gone already!
sorry to bug you cats by name but I might have caught a teet in the wringer. @commando1, @twostick, @azblackhemi, @300rag, @cantflip, and @70bigblockdodge
PD 4501 trudging along. No issues other than at the end of line when it comes to upfitting. more later.
This is about 4903, my "Buffalo" bus. All it still needs is minor stuff, plus painting/stainless buff. This year .. I keep saying that to make myself get it done.
My point. Whisperer is in Italy with his better half. I know one/all of you guys know more than me about old diesels .. your contributions are all over this thread.
Last started 4903 October last year. Batteries out and at my house. Went to start today, all went well, then it wouldn't shut off.
NOT a runaway, just idling calmly but engine stop switch was NOT working. I had a friend with me, but between us it would be hard to tell who's "dumb" or "dumber" on diesels.
I kept hearing a "click and a puff of air" when trying to shut it off. My friend said its "coming from the back, under that door". The rear engine hatch. So I put him in the seat and told him to toggle the shutoff switch while I opened the engine hatch and tried to ID source of the puff of air.
Again, just idling smoothly but I was starting to panic. No diesel will run without air, but without specific knowledge it aint obvious to a noob how that's (denying it air) done on a big, honkin' 9 Liter, supercharged, 8V-71 Detroit.
Pictures below tell a short story, then I am looking for advice.
Orange arrow is pointing to the "thing" that was clicking and hissing when the shut off switch was activated. The silver "plunger-thing" was trying to extend and push on that comma-shaped "lever-thing" -- but it wasn't doing it very well. It has an a air connection at the back end.
Closeup below. The orange circle is where "air" seemed to be leaking from the silver "plunger-thing" around its circumference. It was rather obvious to me that I had to pull comma-shaped "lever-thing" to the right by hand (it moved freely but did NOT feel "loose" to me).
Shut right off instantly.
A calmness set over me .. didn't know anything about anything and lucked up on the solution. I think -- I didn't try to start it again tho.
When I got home and consulted my PD 4903 Manual, I believe the "plunger-thing" is the "engine shut-down cylinder". I think it needs repair or replacement. Doesn't seem to be building sufficient air pressure to fully extend the piston to shut off the bus.
Whisperer told me once most parts like this can be rebuilt - so don't run out and buy everything -- if I could even find it -- like we did on the PD 4501 fan (got ONE replacement part, rebuilt the unit).
Questions for you cats (or anyone with a view?) to noodle on if you can?
1. Is this the malfunctioning part I think it is? 2. Do you think it can, if so, be rebuilt, OR should I try to find a "new" one? 3. Other issues I should consider?
I consider the successful shutdown to be evidence of a potential fix. Any input is appreciated in advance.

From your description it sure sounds like the leaking cylinder has to be the problem. From the breakdown it looks like it has a cup similar to a wheel cylinder. Looks like a simple process providing you can find the parts.

How much further did you have to pull the lever and did the plunger follow it? That leak definitely needs to be addressed but you need to confirm the plunger has enough travel to actually push the lever to the fully off position. As long as nothing is loose in the shut off linkage ie the lever is tight on the the shaft it's attached too and the cylinder is not flopping around in its bracket you should be good on the mechanical side and the problem is the leak won't let it push the plunger hard enough to push the lever against the internal spring pressure.
I think those pneumatic cylinders are a fairly generic part so if you can't find a source for that cup seal to rebuild yours, a new one shouldn't be to difficult to source from an industrial supply store if "normal" bus/truck supply stores can't help you. Just measure the stroke to get you what will work.

Is this a diesel by any chance? Big engine?
If it is, it's probably like the DAF 1160 we have at the university. It's very simple, since diesel fuel doesn't need sparkplugs but relies on compression alone for combustion, it will just keep going. All it needs is compression, fuel, and air. So even if you disconnect the battery it will keep running.
So how do you turn these things off? Equally simple, you just close off the air intake. That's what that cilinder does, it (should) moves an arm which (should) closes a valve on the intake. No more air so the engine shuts off.
So don't worry about it, this has happened to me before as well. No need to panic.
If you're unsuccessful in fixing the pneumatic cilinder you can always convert to an electric solenoid. Run some wires up front with a dedicated "engine off" switch.

Hey! Check with the Bus Grease Monkey guy in Tennessee. He has a YouTube channel and his most recent video was about an engine that also would not shut down.
https://www.youtube.com/@BusGreaseMonkey
@67newport and @Ripinator .. i haven't yet plugged into the Bus Grease Monkey yet. His market niche is exactly what I have. thanks for the reminder.
There are 2-3 folks I know of who specialize ONLY in the old two-stroke Detroits .. all the 50's & 60's PD's had them. I am UN-likely to get anything newer than that vintage bus.
There's probably a 100 folks I have run across the past 10 years who hobby around but who ALSO have deep expertise to work on them when they need to. Anytime somebody touches my stuff its $150/hour.
My reliance has been on folks I know .. but the fellas working on my Scenicruiser are NOT "experts at the old stuff.".
They are HIGHLY skilled, but they have a HD client base .. folks making a living driving, and with "new" product (post 1990's vintage), broke down on the road, and every minute laid up is money lost to them.
I keep getting pushed aside .. and I am fine conceptually .. by those jobs.
Plus, honestly, my guy really ain't the same (personally and professionally) since he lost his wife during the pandemic in 2020 .. in his business, plus being "office manager", she was the one working with local folks like me with old stuff (chasing parts, getting our stuff into the schedule, doing follow-ups, etc).
He had the mechanical assignment .. the upfitting was always gonna go to some other folks. We got WAY behind on the mechanical, this the overheating blew up last year, so the upfitting fell equally behind.
My point .. once both my PD's are roadworthy to cross the country, AND I retire finally (coming soon) AND stay healthy, things will pick up. BUT, it will always be somethin with this old iron we hobbyists have to deal with. A trip to Tennessee and other places is in my future.

Mighty fine. Also, I'm not sure if you are aware, but the Bus Grease Monkey offers a significant discount on labor when you come and do the work yourself using his tools, etc. under his guidance.
