I have been looking at a number of trailers and have been trying to be flexible so as to give myself more choices for trailer purchase. I know that seems odd as most people try and narrow their choice...
Unlike Dan, we don't bother to dry it. When we make our last stop to dump the tanks, my wife hoses down the inside, sprays it down with cleanser, wipes it down with a sponge, then rinses it off. By the time she's done, I'm ready to dump the grey tank. I wish it was that easy at home. ;)
