Installing second battery group 24 Odyssey
on a 2021 1500 chevy crewcab high country. Ordered battery tray and welded angle iron on both mounting sides and ordered custom square bolts to secure to frame. The way under body is i will still have 3" of clearance on top and the tray will be 1" below frame which is still higher up then.other stuff. You can be even with frame if go with group 34 battery but this group is not popular and most are customer order and not as good as group 24. Hooking up multi mount winch cable front and back. Using cole hersee smart isolator P/N 48530 they work fantastic and reliable. Have one in a truck going on 14 years and no issues. Install momentary switch if starter battery goes dead hit the switch and current reverses and supplies power to starter battery to start your rig.
