I currently own a Fleetwood Revolution 39 ft 350 Cummins. Looking at downsizing to something smaller. I desire some feedback regarding pro's and con's of a gas versus a diesel RV. I understand that there is a difference in torque and horsepower. However, doesn't the cost savings in fuel outweigh those advantages. Are there any specific gas engines I should stay away from during the research phase. Any feedback would be greatly appreciated.

The only gas class A's currently produced are on a ford f53 chassis.While these are fine motorhomes, and have gotten better in recent years...The engine sits between you and the missus, and likes to rev (rendering conversation difficult)and the chassis is on leaf springs, not air bags.Cost, IMHO, is a non issue. For every person who says a gasser is cheaper to run because gas costs a few cents a gallon less, there will be 6 who say a diesel is cheaper to run cause they get better mileage (even though they cost 4 times more to buy in the first place) :)The "big thing" these days is smaller DP's, there are a number of 32-36 foot diesel pushers being produced today that could be very nice.

I downsized from a 40' DP to a 31' class A Winnebago gasser and had no regrets. Don't let people here tell you all gas engines up front are noisy. My Winnebago was as quiet as a passenger automobile. Good luck!

Test drive what you like and don't worry about what anybody else says. Try the gas vehicle and see if it fits your needs. You are the one with the bucks, buy what YOU like.Good luck, safe travels,MM.

There will always be those on each side of this issue that are adamant that one or the other is the only way to go. I have one foot in each realm. We have a new 2014 Tiffin Allegro gasser. I love our new motorhome. I love the floor plan. It is a big improvement over our 32 ft Class C. But of course that filled our needs 'then'. I researched the day lights out of gas vs diesel. If the price difference had been closer, we would have gone with diesel. I just couldn't see spending that much more for the diesel torque. Our current coach is fulfilling what we are doing these days. But, we are already discussing that when we trade this coach in a few years, we think we would like to step up to a diesel. I think if you have had a diesel, you may find yourself disappointed in the lower power of a gas engine. I fully understand wanting less coach to maneuver size wise. We don't plan to ever get a larger unit then our current 36 ft.

Our 2011 G'town 29' gasser was loud and hot. We put insulation under the doghouse & floorboard which helped slightly. The best thing we did though was sell it and buy a DP. We went up slightly in size but made a huge leap in quality with a 2011 Newmar Ventana. No more engine screaming under our hot feet and we can have a conversation without shouting to be heard.Our Ventana is just over 34' and while bigger than our gasser, it's still pretty small for a DP.
