WEll- I wasn't really boondocking. I was in a state park with electric and there was a water spiget about 50 yards away and I didn't have that much hose or a "cheater" even if i had. But, what I DID have was a little 12 volt pump that I got at harbor freight as a result of a suggestion by Jack and so I just filled up my collapsible water jug a couple of times as well as a small cooler that holds about two gallons and, like, wow, that is a very slick set-up. Had to pull a couple of screws on my battery box to get to the lid up to get a clear shot at the negative terminals ( I'll work around this by next time out...)---- but that little pump moves water very quickly into the tank. And, it is quite compact and unobtrusive. So- Thanks jack.
