Just acquired a new motorhome . . . our first. I'll be planning on
installing a two meter radio in the cab area ( it a Class C motorhome ),
and would also like to put an HF antenna somewhere on the rig.

I have very little idea what the norm is for mobile operation antenna
installations on these fibreglass body rigs, no do I have any idea at
present where coax lines are run and routed into these rigs. I can
probably figure out something for fixed operation, but not sure on mobile.
Any suggestions?

A small dual-band magmount will get out nicely. Mounting and counterpoise
can come both-at-once. Get some fixture adhesive from the hardware store
and lay down a glob on the roof. I guess you can use RTV or caulk, but I
never tried them. Then, take a steel TV tray or some other piece of sheet
steel about two feet across and push it into the glob of fixture adhesive.
Presto! Mag mount sticks to its counterpoise. If I were you, I'd check for
magnetic properties and VSWR before even opening the fixture adhesive. What
worked for me might not work for you. Aluminum is no good -- nonmagnetic --
and some variants of stainless steel are also non-magnetic.
