how to improve?
Hi, this is my first post, and I'm brand new to RVing. I just bought a 2009 Keystone Sprinter Select 29BH. The dry weight is 6520 pounds, and I'd say I've stored about 150 LBS in it when towing. So far I've only taken it camping one time, and I think I got only about 7 miles to the gallon, and I drove about 62 or 63 MPH (is that the speed others tend to drive?).
I have a 2001 Yukon XL 1/2 ton with 3.73 gears, and the 5.3 (323 CID), and no modifications at all. I also have a trailer hitch with sway bars, which helps a lot.
My question is, what kind of mileage improvements have each of you been able to accomplish? What types improvements have proven wasteful? Which ones have given you the most gains?
By improvements, I'm suggesting, camshaft swaps, computer chips, headers, cat-back exhaust, air delivery to intake, etc.
I ask because I don't want to rush out and buy a newtruck with a higher towing capacity when I can just keep my Yukon and do some work to it.
Thank you in advance.
