Wondering what I can expecting in MPG for an RV listed for sale in town. The price is right but the age and possible gas cost is daunting. Thanks for the help!
I have a D22 with the 318 and after several trips the longest so far being 500mi, I am getting around 7.5mpg and just like you I was quite disappointed.
I purchased the motorhome several months ago and it already had been upgraded with a new intake and carb and a dual exhaust so my expectations were high.The guy I bought it from must also have been high because he said he could get 12mpg while towing a car!! HA! HA! Must have been going down a really steep hill. I have checked the position of the choke (manual choke) and it is fine. I also removed several spark plugs and it appears to be firing normal.
I am very pleased with power and how engine runs overall but fuel mileage is not what I expected, but when you factor in the added comfort and the savings on hotel rooms I guess I can’t complain.
