Just got home with our new Pod. Couldn't help but notice the battery was held on the front frame member by a strap and a prayer. The only thing missing was a sign, "$100.00 battery, free for the taking".
I needed a secure place to keep two batteries, a selector switch, and maybe room for wheel chocks, hitch locks, etc. I bolted a metal tool box to a new angle iron cross member. I insulated the battery compartment with rubber garage floor tiles (Lowes). I added a divider to secure the batteries and make a second compartment.
I hope the pictures come through.
