Forgive my ignorance, but I am so new to 5th wheeling that I haven't yet even taken delivery of my unit. However, I have purchased all of the essentials and have started organizing storage bins. The one question I am perplexed with is ... How does one transport the sewer kit, once it has been used in order to not stink up everything else in the bay. I have purchased the Rhino Flex Sewer Kit, complete with bayonette fittings, etc. It's nicely tucked away in it's box at the moment, but I have been wondering how one finds a tupperware bin air-tight enough to store and haul it without eventually having a problem. Is it simply a matter of continually flushing fresh water through the tanks until it is relatively clean?
