Transferring fresh water when dry camping

I bought a 25 gallon spray rig from Northern Tool. I took off the spray hose and installed a quick connect water hose fitting. I took off the alligator clips from the electrical wires and replaced them with a regular 7 blade rv plug. The tank is strapped in front of my fifth wheel hitch. If my camper tank get low, I just hook up my electrical plug and water hose and refill my camper tank. My particular pump is not the fastest but it will empty the tank fast enough for me. I also have 4 of the green 6 gallon jugs that I used to use that I can now just pout into my 25 gallon tank if necessary
