Sounds like you are going to have some fun RVing.  Depending if the 40 ft 
coach is made of fiberglass or aluminum you might just make out with the 
vehicle itself as a counterpoise, something you can easily try and if it 
don't work try the hamsticks.  I am assuming that you will be parking in 
campgrounds where space may be limited preventing connecting elevated 
radials of 1/4 wave length.

Happy trails,
73, Jim, wd4air
