You said handy dandy, so here goes. My daughter was visiting on short notice and wanted to stay in the TT. We don't have an outside hose. If we had known she was coming, we would have filled up the holding tank at the last campground. So...
Kroger was closing out their summer items. I picked up two 2 1/2 gallon plastic watering cans at half price - about 8 bucks total. I took off the plastic diffusers, filled them with the sprayer at the kitchen sink, and did a few 5 gallon trips across the yard.
They are easier to hold up to the filler tube than the bigger water jugs, imho, because of the 2 handles at the top and the side.
Mine are like the one pictured with a little longer nozzle, but you can find some with very long nozzles as well.
