Reopening this thread, because I'm looking for almost exactly the same type RV as the poster (28ft, Class A Diesel). A lot of the posters recommended against diesel for the individual owner, but I had heard from an experienced RV friend that diesels were a better bet - not because of the engine so much as the transmission. He claimed the automatic transmissions in gas-powered RVs couldn't handle the weight load, and would cause problems, but that diesel transmissions were more sturdy. I'm sure there's exceptions, but anyone care to comment on that as a generality? Right now I'm looking at Allegro Breeze or Serrano, but am worried that both are underpowered.
Thanks much
