Just took our new 28' Prowler travel trailer (5200 lbs dry) out on the weekend. My '02 5.3 Av (410 rear end) pulled it fine, but a little more power would have been nice around some of the hills here in Southern Alberta. Any suggestions on power products would be much appreciated. I figured I got 11 miles to the gallon so any tips that could boost that by a couple miles would also be appreciated.
Thanks in advance
Greg
