The engine torque rating dictates what transmission comes with the coach. A Cummins ISL 8.9L with 1250 ft lbs of torque will come with an Allison MH3000.
A Cummins ISM 450/500hp with 1500 ft lbs of torque, or larger ISX with 1650 ft lbs will come with an Allison MH4000. These will generally be in longer coaches.

Most higher end coaches with a large engine and transmission will be at least 40' long, and many will be 42-45' with a tag axle. There are some exceptions, but they may be rare.

I've owned a short diesel pusher many years ago. When you place a very heavy diesel engine and large Allison transmission behind the rear axle on a short coach they can handle very poorly (tail wagging the dog).

Hope this helps.

I believe your original post stated you wanted to tow 15k . On this note you would be better with the older high end, which has a better chance of having the higher hp and tranny to deal with this high towing capacity. Not many rvs are rated to tow that much, and if you add in all the gear and passengers, it doesnt leave you this much for towing from your gross combined weight
. As stated, you might want to consider going bigger with the coach. The wife is already pulling a long trailer, a couple more feet wont be that much different.

The RV we have now is an Outlaw.
A gas guzzling toy hauler that we bought to use at Burning Man every year.

I am our camp's kitchen lead and I bring the heat in the RV.
The toy hauler carries our camps kitchen equipment. Smoker, oven, sink, stove etc.. All propane and commercial restaurant stuff.

I decided to build an art car for burning man.
Probably a Toyota taco chassis chopped up a bit with a 15k watt pro audio sound system with a freezer to pass out Popsicle during the day with hot box to pass out pizza slices at night.

I need to trailer that thing and the Outlaw cannot pull it plus all of our restaurant equipment plus the new stuff I want to buy.
I am going to go with an enclosed trailer to haul everything from Phoenix to Black Rock City Nevada where the burn is every year.

So now, I want a DP that is crazy strong.
I don't want to ever worry about the engine or tranny due to the demand I put on it. Ultimately, I'd like an 8.9 with Allison 4k so that I can have peace of mind that I have more than I need.

I am not certain how much weight I will be pulling, but I know that if I have room in the trailer, I'll find something to stuff in it.

Our Outlaw is 38' feet long. the back 10 feet is garage which leaves us about 28' of livable space.
So stepping down in total length to 34' is actually a nice jump for us to live in.
I am ok pulling a 24' trailer behind a 40' RV, but in an attempt to reduce the gross weight, and make it easier for my wife to drive (without the trailer) as well as gas, I'd like to keep it smaller. 32-34 would be nice but 36' would be fine.
If I have to suck it up, and go with a 38 footer, I will but I'd rather keep it smaller if possible.

That right there just about sums it up, but I'd be happy to answer any other questions in more detail!

You may want to take a look at some Super C models. Depending on what chassis you can get your engine and transmission you want and be able to tow 15klbs and get good MPG's at the same time.
The trick is finding a used Super C

150K to spend upwards of 200K I would be looking at an older, used Foretravel or Country Coach. Also I would not tow anything 15K with anything less than 39 or 40 foot in length DP or a good sized super C. To the OP good luck in your search.

$160k will get you a nice 2011 Allegro Bus, it meets all your requirements except it's 40' long. There were not many luxury 32-34' coaches made compared to 40' lengths.
