H2 = broken trannys with anything over 7000lbs. I am on my third with my Denali and my buddy's H2 was traded after his first towing a 27 Baja. H2 has no wheelbase and you need load leveling suspension. For my 29 fever on my Denali is horrid. It will tow and handle OK but it will tear up trannys. Save the H2 for the wife.... not to mention about 8 mpg with the H2.
