Well as usual the Forum is a great resource for information. I guess I know what I am going to be putting on my Christmas List this year. Lets just hope I can get $160 worth of "behaving"
in between now and the end of the year so I can get one of those way cool Scangauge things. Then I can watch to see if I should add an additional Tans cooler.
If nothing else I appreciate all the votes that HP is not the ultimate requirement (Thanks MrUkToad). As I mentioned in the original post, I can tolerate the current gas millage I just don't want to go in the hole. Figuring I put over 14,000 miles on the truck this past year and only 1,400 were towing I need to be cautious.
Perhaps the easiest answer would be to do all my traveling in the winter when the air temps are much lower.
