I bought a water tank that I can throw in the back of my truck. I put some PVC plumbing, a valve and a garden hose fitting on it. It's not heavy when empty and I fill it when it is in the back of my truck. With the tank in the truck at a higher elevation than the water fill for the trailer's tank, I can gravity transfer and refill the water tank in the camper by just using a regular water hose. By having this setup, I can take the truck and fetch more water without have to breakdown the trailer and haul it up to the water station.
This came in very handy with our old trailer, it only had something like a 35 gallon water capacity. Our new Eagle has a 80ish gallon water capacity so I won't be needing to chase more water very often.
