I had forgotten to post a photo of the battery box I made for the travel trailer.
Not feeling good about leaving a few hundred dollars worth of batteries on the trailer tongue undefended, I looked at purchasing a lockable double battery box and decided to make this one instead.
Bought a truck tool box for the bed for $50 and cut up the pieces to get the shape I was after. Total material cost (including a new riveter!) was about $150.
Had used a friends sheetmetal equipment to make the top.
Had it on the trailer a couple of weeks ago and still need 4 footman loops to better secure the batteries inside.
