Agreed, I'm not 'dogging' any coaches, at least that wasn't my intention. The original poster asked a specific question, if diesel pushers were sluggish, and I answered that specific question - based on my experience, YES.
I agree, that there is a 'butt for every seat', and diesel pushers definitely have their place and have their advantages. But, they are sluggish compared to a gasser. That is what the original poster asked, and I answered. Thats all.

If you take a new 38-39 ft 3-4 slide 320HP ford Class A MH and loaded for travel and I take my 40 FT pusher with a 425HP Isl and loaded for travel and we take off form a dead stand still I bet you will not get to 60MPH any quicker than I do
