A diesel engine can set for 5-10 years and crank right up with a new battery. Not going to do that with a gas engine. This is even before the sorry gas they are making today.
OP, under 36' you do not need a diesel, but like you said... "the higher quality interior, air ride, and having the engine noise 30+ feet behind" plus a turbo and an exhaust brake.
Obviously you do not have much experience with engines. Since I have restored a lot of old automobiles I can say that I personally have gotten gasoline engines running in a short time, without a tear down, that have been sitting for 20-30 or even 50 years. I am not sure why you think a diesel engine can sit for years and still be in great shape. When I was a contractor I had a lot of diesel equipment and if not properly stored, I would still have to go through the same routine with them to get them running as with the gas powered equipment.
Since the OP plans to use his coach 4-5 times a year, all of the talk about an engine sitting for YEARS does not really apply.
