Here's how I did it. The tank came from Tractor Supply Company (
Click here), and the 120 volt AC water transfer pump came from Lowe's Home Improvement. I opted for the 120 volt (AC) instead of a 12 volt (DC) because I always carry a 400 watt inverter in my truck and can always plug the water pump into it. And when electricity is available, just plug into normal AC power.
I do have to use a water transfer pump because the bed of the truck is about 18 inches lower than the fill port on the camper, and according to the physics class I took in college, I think they said something about the law of gravity and water simply does not run up hill. :B
Filling it from a water source. I fill from the bottom. Because the round cap on the top is one-way vented, I remove it to let air escape, otherwise, it would fill under pressure as water was added.
