X2 on the second pump. We were getting low tonight, and even with heading home tomorrow, we opted to add some. Took about 5 minutes to set everything up, then we added about 13 gallons, in less time than I could even finish a cold one. Cleaned up was about another 5 minutes. Way easier, IMO, than trying to balance a pop bottle beside the trailer. Ours needs some pressure yo get it to the water tank (not gravity)..
