Man I don't know how your H-2 does it , you must have bought an option that mine did not have. I was pulling a 30' Spectre 5 miles to the local lake and mine sucked!! My F-350 dually with a 24' trailer outrun my H-2 empty down the highway. I paid $61,000 for mine, kept it 4 months and lost $6,000. The Hummer dealer can not sell them around here anymore, they have them stacked up like the old Ford escorts. Good luck, I'm glad you like yours.
