Average Class A diesel RV costs ???
Having owned 8 rvs ,we found that the newer units do much better on fuel
the price of a gas rv on the workhorse chassie is much lower than diesel,there are some great ones out there.
, however the diesel has many advantages ,better fuel mileage,
most have air brakes, fuel won't blow up. tune ups at 150,000 miles
(adjust valves) And much better handling/ride
Avoid 19.5 wheels 22.5 or larger handle better& wear better
There are some great buys out there in used pushers about 1/2 the sticker price try not to buy any over 4 yrs old.Ck the warrenty to see if you can transfer it. we hade great luck with Cummings 5.9
pushing a 36 ft ,getting 9.9 to 11 mpg
