If you're tired of driving your mini around kicking up rocks and mud all over your back window and the rest of your bed, then it's time you took matters into your own hands. For less than $100 in materials you could tub-out the bed of your mini-truck to fit any size wheel you're looking to tuck in a matter of a few hours.
We got with Bobby over at Sadistic Iron Werks to give us the rundown on exactly what it takes to tub the rear of a mini. Since many people opt to keep their bridge work out in the open, we wanted to get a feel of the exact process to completely cover just the wheels using simple trailer tubs. The rest of the sheetmetal filler pieces can be quickly measured and fabbed-up for the fully enclosed look. Just like most simple modifications, this process is fairly straightforward as long as you measure twice and cut once.
Follow along and you could be on your way to a much cleaner-looking bed and an even cleaner back window to boot.
1.The main component used is a common trailer fender that you can order from any trailer supply company for less than $25. They work perfectly for tubbin' both the front and rear of any mini-truck. | 
2.This bed happens to already have a spray-in bedliner, but no worries, a few precise blows with the mallet and we're good to go. |
3.The rest of the coating is stripped away using a wire wheel. | 
4.Once all of the spot welds holding the factory tubs in place are apparent, they can be drilled out. |
5.For the top of the stock tub you'll need to gouge away the lining enough to plasma-cut the rest of the tub away. | 
6.Here's a look at the tub completely removed. Bobby removed the stock tubs before he 'bagged the truck, since he knew they had to go already. |

8.After the truck was 'bagged, he could now bolt on the wheel and see how far up the tubs would need to go. All necessary measurements were taken to see how much space the tubs would actually need to occupy. |
9.Once all the appropriate measurements are taken, you can clean up all the areas that will need to be welded up. | 
10.Obviously the tubs only cover the wheels, so filler pieces will need to be made for the rest of the spots. |
11.After taking the measurements, it's easy to build templates for the outer surfaces. | 
12.Trace your template onto the sheetmetal and cut it out. |
13.To make things as clean as possible, it's best to use to punch holes spaced along the outside to tack the piece into place. | 
14.Clamp the filler pieces into place and weld the punch holes. Repeat these steps for all necessary filler pieces. |
