It's not the tourist RVs that are the problem per say, it's the local rat dump RVs and cabover campers that are the eyesore and health havoc problem.  Locals dump their sewer and trash all over the Walmart on A Street parking lot.  As long as the RVs don't over encroach in the retail parking lots, which is a likely threat to the locals, then I say leave them alone.  Charge them a sales tax instead.  Heh, heh.
