You didn't mention what model or year H3 you have or what you intend to pull it behind.
A quick look at the 2010 models shows they range from 4,500 lbs for the base model to over 6,000 lbs for the top of the line model. If you have the top of the line one it's to heavy to tow behind a gas motorhome. If you have a DP there's no problem as far as weight is concerned. There have been several posts regarding towing Hummers and the biggest watchout most have addressed is a potential problem the braking system.
There's a potential issue if you have the "active braking system". If yours has active braking it essentially has power brakes that operate regardless of whether the ignition is on or off. That's good for the driver but not so good if you intend to add a remote or coach powered braking system.
Most add on braking systems are meant to be operated on a vehicle with a "dead pedal" which means no power assist when the ignition is off. They press hard enough on the brake pedal to apply the brakes without power assist. If they are installed on a vehicle with active brakes without also installing a pressure limiting device they will lock up the brakes.
