I have a custom under body battery bracket I made for my 2013 Ford E series EB. My son owns the van now and we did a complete redesign high roof and new layout he did not want to use it in the new build. It mounts on the passenger side under side doors same area as a factory Aux battery box would be. I am in Florida not sure it’s worth shipping but if someone wants it available. The picture with the batteries is what it looked like when we took it out.
