I did notice the added weight going over the passes though, and got about 10mpg all weekend. Guess that's the tradeoff with bringing a lot of stuff with you. It's a little low on the tongue side, but a new rear bumper on the 100 should raise that an inch or two, if that's not enough I can always lift a little more, or go air bags or something. Or just not worry about it.
