I use a hamstick dipole to avoid groundplane issues. Your electrical grounding plan seems sufficient given that you're in an RV. WATCH OUT FOR UNDERGROUND ELECTRICAL SERVICE LINES when driving your ground rod in an RV park--also water and sewer lines. It is probably a good idea to get permission from the park management, which may, or more likely, may not be granted.
