Go with a Barker, and go with the largest size you're willing to pay. Do a search online for the best price. I just purchased the 42 gallon Barker and it was delivered in about 3 days from RvpartsCountry.com. I had the 30 gallon Barker, and needed a larger capacity. I sold my 30 gal on Craigslist in a day. The main reason I have a tote is when I want to go somewhere without full hook-ups, I can go without the hassle of hitching up just to go dump. Some of best scenery out there doesn't have full hook-ups. Good luck
