If you're like me, waxing your RV can be a pain. I recently found a product that enables us to wax our RV's easily, without water and ladders. I've ordered it and like it. The product is called Wash Wax All. I've included a link to their website so you can view the product and video.
By the way, I have no affiliation with them at all. I'm just posting it in hopes that it may help some people.
