OK, back on topic. The only way you can know for sure is to measure. The two measurements that are vital is bed clearance and levelness of the trailer. In order for someone here to answer your question, they would have to have the exact same equipment in terms of TV, trailer, hitch and pin. That's not impossible but it does make coming up with the exact combination a bit harder.

Measure the bed height of your old truck, the hitch height and the inside bed height. Then measure the bed and inside bed heights of the trucks you are looking at to see what the difference is. Disregard what I said about the springs on the SRW and Dually being the same because of the wheel/tire differences effecting the height, so measure both. Then you can to look at the options you have to bring everything back in line. But first you need to establish whether there is a problem. If yes, come on back with the amount of difference so we can discuss your alternatives. Most hitches and pin boxes have adjustments, and there are other alternatives too.

EDIT: I just went to the GMC website and they give the inside bed dimension for all beds as being 21". Unfortunately they don't give bed heights from the ground, so you'll still need to measure those.
