Your camper system is a low pressure system. That is; the regulator is at the tanks. Any propane grill will work, such as a coleman grill, but you have to remove the regulator and run connect directly to the propane line. That is usually where the problem comes in, removing the regulator and being able to still connect to the propane line. I've done it for my RoadTrip grill, but it's not easy or cheap. It would probably be cheaper to carry and extra 20 lb propane tank. Also, you can probably get a replacement grill from your RV dealer; albeit, it would still be a cheaply made grill that costs too much.
