On the Chevy chassis with the 5k rating, can those hitches be upgraded to 7500?
You have to look at the capacity of the chassis. The chassis is rated to support a certain weight. Subtract the weight of the coach including all the stuff you bring camping from the chassis rating weight and that's the towing capacity of your rig.
I don't believe the Chevy chassis is rated high enough to tow 7500 #.
