I recently purchased a 2014 Tuscany 36MQ. I am now trying to understand a little more about the electrical system. I understand that while driving that the chassis and house batteries are tied together for charging. I also understand that only the house batteries are charged by the Magnum Charger/Inverter when connected to shore power (or generator). I am looking for a solution to maintain a charge on the chassis batteries when connected to shore power. Here are the options being considered:

1. Use a Battery Tender that will plug into one of the coach's outlets.

2. Install the Magnum Smart Battery Combiner (Model ME-SBC) that uses a three wire connection (one to each battery bank positive terminal and one to a common ground).

Option 2 is obviously more expense but can supply more amps and will work automatically when connected to shore power or with the generator working.

If anyone has any experience or suggestions, it would be appreciated.
