Hi BFL,
No, it is really about designing a solar system that will properly maintain the battery bank including equalization. If that is done there is no need for extreme desulphation at the end of the trip.
There is no "one size" fits all. A full timer can justify a whole passel of solar particularly if they boondock a lot. They should lean towards "supplying daily needs" plus about 60 watts per 100 amp-hours.
A weekend warrior needs far less, so long as there is enough to equalize. When they get home the system will take care of itself.
BTW my rv is in getting a new master cylinder for the brakes. (must have been your mountains? *grin*) and the solar system is putting out 1.1 amps.
