I have a mechanic friend who is also an RVer (an SOB) who always makes fun of me when I discuss things I have done to try to improve my Gas mileage on the motorhome. Although he admits that things like the 3.70 final drive and the MSD ignition will make incremental differences in my fuel economy (kind of an oxymoron in this case) he contends that they will not save me enough mopney on gas to ever pay for themselves and that if I were making these improvements strictly to save gas (which I'm not), that would be silly. I have to admit, he's right.

There are certain factors of physics that will prevent a motorhome from getting wonderful fuel economy. If I had taken the 30+ mpg engine out of my wife's '97 Saturn, for instance, and put it in my GMC, it would certainly not get very good gas mileage or last very long, much less provide any level of usable power. I have a 2000 Dodge, 1-ton utility truck with a multi-port, computerized fuel injected 8 litre (488 ci) V-10 in it. It has a modern overdrive transmission and weighs about 10,000 pounds. It barely gets any better gas mileage than my '75 GMC.

As far as I know, the only conversions that have given anyone substantially better fuel economy, in a GMC Motorhome, have been diesels. I don't believe they will will prove economically feasible for most of us though. If you want economy, buy a Sprinter or VW based motorhome, not a GMC
