Some good techniques and some old links still applicable...I think I'll leave shore power plugged in with the converter I have.
smkeetner - I've got an Progressive Dynamics, Inteli Power 9200. From the documentation it can "boost" the battery up to 14.4 V but in "storage" mode it keeps a constant 13.2V to keep the batteries from gassing (preventing water loss). That's what I like about it - it seems to do the job in an outstanding manner! Batteries are always it top shape for any excursion.
BL - I think it all depends on the converter.
As for other necessities -- water I always empty the tank. Same for the gray and black regardless of the duration of down-time (storage) between trips.
