Well, the problem with the filter turned out to be that we forgot to run water through (or "flush") it for a while before hooking it up to the trailer, and so the charcoal dust clogged up the works. Thorin managed to clear out most of it, but he couldn't do anything about water line that led to the toilet, so we have to improvise when flushing (it involves using the water from the hand-held shower head). As if having just one bathroom with six people wasn't already awkward enough!
And then there's the issue of the kitty litter box that is in the boys' room, which is next to the bathroom, and happens to be the hottest room in the trailer. There's really not enough air freshener in the world to improve the atmosphere back there, and we're thinking of putting the litter box in the bathroom shower/tub, instead, where there is at least a ventilation fan. It isn't like we are going to be using the shower any time soon, anyway, because of the need to drive the trailer over to the pumping station whenever the tanks get full.
There is, at least, a shower-house nearby (next to the laundromat that we won't be using until we get quarters), so we're able to get ourselves cleaned up with little trouble. Well, except that it is fairly difficult to get Gimli out of the trailer at all, and there are quite a few spiders (and mosquitoes, and biting flies) in the shower-house, itself. And Frodo is rather scared of the place, in general, because there's an echo. And the flow in the showers there is really too low (and the water is pretty hard, as well) so it is difficult to get all of the shampoo out of our hair. But other than that, no problem!
