Yes...the T-100 roof is metal...unless you have a moon/sun roof installed. 
If you have a fiberglass camper top, it would be an ideal place under there.
I think yer best bet is to mount the antenna when you need to use it and stow it when yer not. Other than that...there's not much else you can do since it's a truck.
