I'm on my 3rd Hummer (now called H1). The current is a '97 Turbo Diesel w/ a 2in. lift and 38 Swampers on the front and PJ Dirt Gripz on the rear. I avg. about 15 mpg and regularly tow my 30 Cobra w/ no problems. I just picked up a new '02 PSD Excursion on Friday and love it. Can't wait to tow w/ it and leave the Hummer for offroading.
