Man you did an awesome job on that SS. My only critique is pertaining to the grommets you used in the trunks floor. When you were underneath showing the gound installs. You could see alot of daylight into the trunk around the wires. That could lead to water getting inside the trunk near the battery bank. I recommend either waterproofing the holes with some silicone or using those waterproofing grommets.
Excellent work. I do have a question. I thought with any additional battery, an isolator was needed ? Also what keeps it from sliding towards the rear, I know side to side and forward is taken care of.
Highly recommended if your running lithium battery mixed with regular or AGM batteries up front because they don’t work together and will ether catch on fire 🔥 or kills the lithium far as the box goes inside the truck towards the back the floor curves up slightly enough too were it doesn’t move
