We don't boon dock but sometimes we can run out of water on extended stays at the state parks where you can only fill at the water stations, I have hooked our RW up to the truck, visited the dump station then refilled the fresh tank in the middle of a long trip but also like to sometimes fill it up without moving the RW. I came up with this 30 or 40 gallon tank system. I used plywood around one end to house the components and added plywood strips in a few locations to allow the tank to lay flat in the bed of the truck. This will fit between my hitch and the tri-fold tonneau cover without changing anything. Gets the power from the 7 way plug on the back of the truck. Powers up when the key is on. Used a 10 amp fuse for protection. Used a normal rv gravity fill fitting which also has the bug screened vent fitting. A switch to turn on and off. A long hose to reach about where ever it needs to fill up and a 1/4 valve to stop the flow of water when your tank is full. When the pump builds to 45 psi it shuts off anyway. I don't have an auxillary tank in our bed of our truck so this doesn't get in the way. I use a few pieces of firewood to keep it from shifting while driving. If I need to use the tank, I simply remove the wood and pull the tank closer so it is convenient to use. Drive to the water filling station and fill the tank using a household type whole house water filter like what is already on board the RW. We filter the water before filling the potable water and also when filling this tank. We like clean water, drink the water and use it for coffee and the ice maker. I have also used this to help fill friends and family members water tanks if needed.
