2007 HUMMER H2 tailgate

Your spare tire carrier is behind the tailgate.
If your hitch extension is too short, the spare tire
may interfere with trailer coupling or trailer
tongue jack operation on some types of trailers.
After you’ve loaded your trailer, weigh the
trailer and then the tongue, separately, to see if
the weights are proper. If they aren’t, you may be
able to get them right simply by moving some
items around in the trailer.
Trailering may also be limited by the vehicle’s ability
to carry tongue weight. Tongue weight cannot
cause the vehicle to exceed the GVWR (Gross
Vehicle Weight Rating) or the RGAWR (Rear Gross
Axle Weight Rating). The effect of additional weight
may reduce your trailering capacity more than the
total of the additional weight.
Consider the following example:
A vehicle model base weight is 5,500 lbs
(2 495 kg); 2,800 lbs (1 270 kg) at the front
axle and 2,700 lbs (1 225 kg) at the rear axle.It has a GVWR of 7,200 lbs (3 266 kg), a RGAWR
of 4,000 lbs (1 814 kg) and a GCWR (Gross
Combination Weight Rating) of 14,000 lbs
(6 350 kg). The trailer rating should be:
You can expect tongue weight to be at least
10 percent of trailer weight (850 lbs (386 kg)) and
because the weight is applied well behind the rear
axle, the effect on the rear axle will be greater than
just the weight itself, as much as 1.5 times as much.
The weight at the rear axle could be 850 lbs
(386 kg) X 1.5 = 1,275 lbs (578 kg). Since the rear
axle already weighs 2,700 lbs (1 225 kg), adding
1,275 lbs (578 kg) brings the total to 3,975 lbs
(1 803 kg). This is very close to, but within the limit
for RGAWR as well. The vehicle is set to trailer up
to 8,500 lbs (3 856 kg).
