Ive only gotten to camp in my NTU twice, outside of Camp Driveway, since buying it in January. Once with full hookups and once with out sewer hookups and had to use my inherited "blue-boy" for gray water. Mine is a 10 gallon, I think. I say I think because it sure seems like it weighs waayyy more than 80lbs when its full. It has wheels and a handle. Id take a pic but its stored under my U-couch right now. Anyway.... on day three of our trip, the tote was full of sink water. I know I know, that seems like a lot, but we have a baby and its a lot of bottle washing many times a day . I unhooked the blue-boy from the pup and wheeled it over to my 4Runner rear hatch. The thing is so awkward when full it literally took everything, and I mean EVERYTHING, I had to lift it into the SUV. Same for getting it out at the dump station. Ive been dreading having to use it again. I also don't want to have to dump it daily, with the less than full tote, or a smaller container. I happen to come across this little bracket on Amazon that allows you to slowly tow your tote and I just wanted to pass it along in case anyone else struggles with a full wastewater tote. http://www.amazon.com/Barker-16362-Towing-Bracket-Tote/dp/B007HRMZUM/ref=cm_cr_pr_product_top?ie=UTF8&colid=32NES4UAB0GHI&coliid=I2J5Q8KQO6NI7L Strangely, only 16$ on Amazon, and over $30 on ebay.
