Since you obviously have A/C voltage available I will make the assumption that you have 120V available. Buy your self a Battery Tender Jr. (.75A) or low amperage maintainer of your choice and hardwire it to your chassis battery(s). Set the charging head somewhere that it is easily accessible. Mine were located in the same compartment as my house cable. When you pull in to storage turn off your battery disconnects, plug the head of the BT Jr in and forget about it. I had one on the house and one on the chassis batteries and my original batteries lasted over 6 years. I use BT Jrs on everything I own and usually pay around $22.00/unit.
