Here is my work wagon. It is a 14' Cargo Mate cargo trailer with dual axles. Its been a work in progress over the past two years and is ever evolving.
My work bench inside. The countertop is very nice for cleaning tools and working on prefab work. I have a charging shelf above for keeping my M28 charger, M12 charger, Milwaukee 4V Ni-Cd charger, Makita 18V LXT dual bay charger, Milwaukee M18/M12 SuperCharger, a multi-port usb charger and my Milwaukee USB charger and power supply.
I use the computer a lot for reviewing plans and spec sheets, working on 'as-builts', writing work emails & work orders as well as occasionally modifying PLC programs as needed when I'm working on industrial controls.
Tool box for storing 'specialty' tools that I do not use every day and don't keep in toolbags.
Shelf under the work bench that I use for storing extra consumables and a few tools.
Tool & consumable shelves.
I built the back set of slant shelves are for storing tools in cases, most of my commonly accessed tools and for storing tool cases that have some weight to them. Between the side of the shelf and the back door, I built a holder for my 24" ~ 72" Stabila levels.
Flat shelves for storing consumables on top in bins and various smaller tool cases on the lower shelves
I bought a HF parts rack and built individual shelves for each row of bins to support the bins. I used the metal hanging brackets of the rack and secured them at the back of the shelves to keep the bins in place. Been working great for 2 years without issue.
I put a modular storage rail on the front of the trailer for storing extension cords, my pipe reamers, conduit benders, shovels and various other tools and gear.
The trailer is still a work in progress as I acquire more tools and adapt the layout to better fit my needs.
I bought the trailer used and got a pretty good deal on it. It had been previously used as a mobile hot water pressure washing trailer, so it had a few issues I had to fix when I bought it, but the frame and axles were in great shape.
The original floor was heavily stained with diesel fuel and the smell was very strong. I painted the original floor in block primer and then put down 1/4" finish plywood to cover and seal the original floor.
I also had to patch the hole in the roof, which was used for the heater exhaust, but just covered it with a new sheet of aluminum. I used RTV sealant between the existing roof and the patch and then covered the entire patch in snow roof sealant and haven't had any issues since.
I added a 15A 125V male 3R wall plug on the outside of the trailer for shore power. I used a 20A GFCI receptacle on the inside to add GFCI protection to the charging strips and light inside the trailer.
After 2 years of almost daily use, I am very happy with the project overall and think it fits my needs pretty perfectly.
