I'm just a one man show with a family,wife and 2 kids age 2 and 5. I have a 1979 A class Empress 21' from bumper to bumper pulling a 24ft enclosed trailer with either my 23T-altered(low 8 sec) or 56' Chevy(low 9sec). The motor home has a 440 dodge engine and gets 7 to 8mpg at 60 or 70 mph no mater what the conditions are and what car I have in the trailer.
I'm thinking of rebuilding the engine with an RV cam,alum. intake and headers,wonder if my mileage would improve?
I'm just small time but I bring the family with me all the time and they love it!
