Buying a Northwood Nash from a private seller

20 watts should keep a charged battery charged if there are no loads on it, and under decent conditions probably could keep up with unavoidable base loads like the propane detector and radio memory/clock and so forth. It isn't all that much value for camping, but could be quite handy if you store the trailer someplace where there's light but not electricity; it would mean you don't have to take the battery out and put it on a maintainer elsewhere (or replace it frequently because it self-discharges to oblivion).
