Yes, I have the 92 gallon RDS tank. It works very well. Its gravity fed, and put a shutoff valve on the line. The kit works fine. Once we made it from San Antonio, Tx to Albuquerque without a refill towing a 35' Carriage. We currently made it today from Ogden,Ut to Great Falls, Mt., 536 miles and still have plenty. I don't know how many gallons until I fill up tomorrow. Go for the biggest you can deal with. Good Luck
