The differences are:
* Diesel cost more (this is the only consideration).
* Diesel mileage is better then gas. I got 6.5 mpg on my 31' class-C and now get 10.5 mpg on my 40' class-A.
* Diesel's have way better torque, and that is what gets you up a mountain.
* 250,000 miles on a diesel is nothing; a gasser will have had problems achieving this.
* Most diesel RV's are pushers. After driving a gasser; the quietness when driving a pusher is breath taking.
Yes , good points, to yearly service your diesel pusher, it'll cost around $600. That's what I spent at factory service in Gaffney, S.C. Having said that , I been driving semi's over 40 years, mainly cummings engines, rarely a serious problem, .
V 10 fords , I had one , poor mpg, engine itself I think pretty much bullet proof up to 90,000 miles. But let's face it probability of putting more than 50k on a motorhome isn't likely overall . I'll take the diesel everytime. They are very quite an smooth
Side note, I have run diesels over 500,000 miles, with nothing more than a tune up an regular services
