As a former city planner I can tell you somebody talked to a council member or city manager to get this on the radar. I encoyrage you to make an appointment with one or all the elected officials. Often these matters go before the planning and zoning boards for recommendation before they go to counsil for a vote. Find out your process and meet with those who make these decisions. Come armed with pics and so forth and at the very least if you think you are going to lose, suggest ways to allow you time to load and unload your RV at your home. I have seen subdivision regs give folks a 4 or 5 day window before and after trips and so forth. A letter is not going to get it here, meetings might and if you can hire a land use attorney bring him or her too. Good luck with fighting this soft tyranny......
