Will the camper shell give me a good enough ground plane for a uhf and vhf antenna? Do i still need to ground it to frame? How far apart do i need to space the two antenna's. Thanks for all the help.

Only if it is metallic which I'm sure it isn't. You have a few choices.

You could place a 2 foot square piece of aluminum under the antenna, or you could use a few strips of 3M 1181 copper tape underneath. 1/4 wave in length, or longer, but not shorter.

I thought aluminium was metal. Silly me.

Geez, I didn't see the aluminum part. Of course it will work. Spacing isn't all that important, but if I were doing it, I'd use a NMO2/70B and use just one antenna for both.
