    (901) 214-5337, give him a ring and he can answer your questions. The aux battery will not drain from the main cranking battery. It’s protected. I cannot see the crank battery draining because you’d hook up your accessories to the aux

    Solar panel if you park outside. Battery charger running off a 110vac outlet if parked inside. Or both.

    Or just plan on taking a longer drive once a week. Short 10 minute drives is not so good for the rest of the drivetrain either.

    Yeah that’s fair, thanks for the number I’ll give him a quick call to see.... I wouldn’t be running any accessories with the truck off unless I was out doing a trip somewhere, but I’d be concerned about the six battery not staying charged with my short commute

    Nice setup but on top of the battery it will corrode after a while.

    I’m running a dual battery setup on my 4Runner using two Group 35 AGM batteries. It uses a different system (Blue Sea MLC-ACR) but should be very similar none-the-less. I’ve got a National Luna battery monitor on both to check voltages. I run a fridge, off-road lights, and winch off my aux battery.

    You have nothing to worry about. Since you aren’t using a fridge which draws power constantly then there will be little battery drain on the aux battery. You likely aren’t using your LED bars, ham radio, and winch daily. Also assuming a 10 mile commute daily is about 15 minutes (I guess if you lived in LA that could be 2 hours) then that is more than enough to charge up the battery. When I’m out camping for a few days and my aux battery gets low I turn the truck on and idle for 10-15 minutes and its back up to 100%. Likewise I commute about 15 miles a day and the alternator has no problems charging up the aux battery. Also most places you want to go camping are a long drive out anyways, more than enough time for the alternator to charge your aux battery.

    About once a month I top off both batteries using a Noco Genius battery charger. I also charge it up before a long trip and after trips as well. I do plan to add a portable solar suitcase to my setup in the future.

    @Theonlyway How's the Genesis setup working out for you?

    I know this isn’t directed at me, but here’s my $.02.

    Just installed the genesis kit in my 2018 tundra. I love the quality and ease of use Shane from Genesis puts into his products. I’ve run his kit in 2 wranglers and the tundra kit has upgrades from the kits on the wranglers. It just goes to show Shane is continuing to make his product better. I highly recommend their kit. Sure you can peice it together yourself, or you can just buy a proven kit, install it and receive product support for as long as you have the kit.

    Thanks for the feedback, Brian. Definitely looks well made and easy to install. Not exactly cheap, but I think it's worth it to not have to piece it together myself.
