I have a 1973 Dodge Tioga Sportsman. It has a flat roof that Leaks, it doesn't have any plywood just metal roof, insulation, and ceiling.  Can and put plywood up there if so what kind and how thick?

Actually, that was common.  Not just for travel trailers, but also for motor homes!  Yes, you can put plywood up there.  You want it to be lightweight, so you can use 1/4" plywood or luan (if you want a finished look without having to sand the plywood finish and deal with the wood knots in it).

Can I use R-board on my roof instead of plywood?

If you mean rigid sheating, no.  Use plywood or OSB.  Rigid sheating is the weakest.  You want strength.
