Since you are going in a camper I don't see any issue with it. I am assuming you would keep them in a cage in the camper and not let them have free roam of it-that might lead to lost gliders, or gliders getting out of the camper completely.
Again I am assuming that you camp in places where there are hook ups so that you would have AC (for yourselves and your pets) and refrigeration.
Really, how different would it be from them being in a cage in your living room?
Now if you aren't going to be hooked up, and there would be dangers of not having electricity, I wouldn't risk it.
Keep us posted. I travel a lot during the summer and am playing with the idea of taking my gliders too. I don't have a camper though, I do a lot of tent-camping and crashing at family's houses.
