This is a good point that many folks overlook, because they didn't realize that the loaded tongue weight gets subtracted from the TV's "available" payload capacity.
If I were the OP I would take the H3 Hummer to a CAT scale and weigh it (w/full fuel and passengers). Subtract the CAT scale weight from the H3's GVWR (noted on driver's door), the remaining weight will be the available payload capacity for a trailer's loaded tongue weight (not dry weight), the WDH weight (50lbs), and any other weight not accounted for at the CAT scale.
For estimating purposes, figure the recommended loaded tongue weight for a X20E would be 10% to 15% of the estimated (or actual) loaded trailer weight.
Example of a X20E w/GVWR of 4,750lbs: (Published UVW 3,660lb) + ((150lb Ship Weight (estimate)) + (400lbs cargo) = 4,200lbs @ 10% to 15% = 420lb to 630lb loaded tongue weight. Thus the H3 Hummer would require at least 420lbs available payload capacity for just the loaded tongue weight.
Also, please note that published UVW's aren't reflective of a trailer's actual ship weight..., the actual ship weight (UVW) is noted on the yellow sticker on the side of the trailer. Depending on the model/size of a trailer, the ship weight can add another 100lbs to 600lbs on top of the published UVW.

Hopefully this information will help as you evaluate a good trailer match for your H3 Hummer.
