additional battery box for tools

It makes me comfortable to bring a few basic tools along while camping.  Tools tend to be heavy and sometimes dirty or sharp.  Therefore they don't mix well with other stuff.   I purchased a second battery box (same size as the original one).  See accompanying image.  The top has alignment tabs. Once the top is in place, I use the blue strap (shown dangling) to hold everything in place.  

and they probably won't stay dry but i like the idea; i have double batterys so not an option for me; i always question myself on the tools i do bring

I have a set of inexpensive tools, wrenches, sockets, ratchets, pliars I keep rolled up in shop towels I keep in a plastic tub with a snap on lid In the rear pass through storage. I also keep a combo tool kit under the rear dinette seat storage area that has basic screw drivers/torx drivers, Phillips just in case. In the plastic tub in the back I have a folding saw, rope I can use for clothes line. fire starters, a folding plastic 5 gallon water can, hatchet, and the MOST IMPORTANT. roll of duct tape. Happy Campin
