Hello all! Please forgive me if this topic is covered elsewhere, but after much searching I was unable to find the information I am looking for. I’d like to hear from people who have done this on their own and didnt have wiring in place from the dealer/factory. Background: -2019 Rockwood 1640esp -Currently using a small gas/propane generator for camp charging -Looking to get solar in the near future and use generator for backup charging. -2 identical batteries were supplied by the dealer Question: Can anyone help me with adding a second 12v battery to my system. Are there safety/charging concerns? -I would like to add a second battery to the system to increase our capacity while boondocking. -I’d like to have a system that still charges off the 7pin while driving (I’ve read where that can be bad for batteries though) -Is it as simple as wiring in a second battery? -Are voltage regulators necessary? -Any extra fuses? -Did you bypass the factory charging system? If so why and what did you use? Thanks in advance for all your replies! P.S. I’m not lazy... I have a 2yo and would rather not design a system from scratch.
