While installing the auxiliary gas tank plumbing I had plenty of chance to reflect on what thousands of RVr's in my business life gripe about every day. Not enough room in the rig. Well, I discovered 1,840 cubic inches of valuable storage space, right above my nose and far behind the rear tires inside the fender wells. What the hey! If I’m going to put the spare gas tank underneath, why not put a tool box there also?
Behind the gas tank filler pipe I built a 770 cu inch box and then on the opposite side another with 1070 cu inches. Each has a 4" wide by 12" directional hatch door with a Southco locking draw latch. Each compartment has a sheet metal floor and rear wall sealed against the elements. Two pieces of sheet metal for each box is all that is needed. Haven't determined how to seal the doors to make them water resistant yet but I'm fooling with that and I have a wide variety of gaskets on the shelf to work with.
I left the jump seat support / bolt mechanism in place. I do not plan on using those seats but see plenty of use for the mechanism, maybe to secure a refer mount or, bench seat belts or,....
Total cost was $38.00 for the latches and about $12.00 for Dremel cut off wheels. Less expensive latches are available but I like the idea oft helping honest people stay that way. Sheet metal came from the scrap bin. Estimated time involved to do the driver side is about 4 hours. The passenger side took a couple of days including R & D and hunting down the appropriate locks. The sheet metal templates for the one side can be used for the other side. Material cost for the gaskets for the doors shouldn't be over $10.00 retail if that is even necessary.
Today, I will primer-seal and under coat the bottom side of the fenders and complete the installation of the boxes.
