Choosing Gasoline or Diesel Powered?

I only saw one mention of stability of the diesel pusher vs front engine gas. I would think that there would be considerably less trouble with swaying from a diesel pusher than with a heavy front gas. Not so? I have owned a diesel pusher 34' older motorhome (Itasca Suncruiser 1993) which I traded for a fifthwheel (39' Cedar Creek) because we wanted extra room when we lived in it for a year. I found that the fifthwheel was very stable in crosswinds, etc, compared to the motorhome, but I have no experience with a gasser front engine motorhome vs the DP. I am thinking about going back to a motorhome but we have already purchased the diesel truck and fifthwheel so we would take quite a beating in a trade down or else would have to pay too much to boot to go to a newer motorhome. I have seen 2000 - 2001 gassers in the $40k range and 1998 - 1999 diesels in the same range. We're afraid that we will lose too much living space to gain back the convenience of the motorhome.

BTW I have had both diesel motorhome and pickup and the diesel is not that hard to take care of. I change the filters and replaced the fluids on all of my vehicles. I have had more trouble with our 2008 Grand Caravan than with the 2003 Dodge Ram Cummins Turbo Diesel. (I had to put new brake pads around and fix the cooling system on the van already.)
