We use one of those hand operated "bilge" pumps too. I think I bought it online at Cabela's for about $23 or something like that. It's not perfect, as we lose a little water in the "pumping process", but it's certainly a lot better than trying to hoist a 7 gallon container and pour it into the fresh water tank on the side of the TM!
PS: The spell check feature has stopped working, so I hope I've caught all the typos
