If the hitch on your 2007 H2 is a 2-inch size then you can use an adapter/extender like the Curt Hitch Extender # C45796. However, you need to be aware that use of any extender will reduce your hitch's tongue weight and towing weight ratings by 50-percent.

This loss of hitch capacity results from the change in the geometry of the forces on the hitch. In the same way that slipping a length of pipe over a tire iron gives you more leverage to loosen a stubborn lug nut, using an extender on a hitch will place greater stresses on the hitch.

So, for example if your hitch has a 500-lb tongue weight rating (as indicated on its safety sticker) then when you use the Curt extender its capacity will drop to 250-lbs. You will need to be sure that your application will not exceed the reduced hitch capacity.
