Welding Office | 2012 Chevrolet 3500HD

This Chevy Carries All the Work Tools Needed for Onsite Repairs

Cory Therrien’s office rolls on four wheels. This ’12 Chevy 3500HD pickup serves as his portable welding truck, and it packs all his tools and equipment necessary to get the job done. When he’s not working, the skid comes out and the truck packs his quad, snowmobile, and sometimes his holiday trailer.

Cory welds mostly in oilfield construction. He’s only 21 but has been welding professionally for five years. In the past two years, he’s owned four brand-new trucks and has lots of nice toys. He works hard and is very proud of his accomplishments.

In the past, he’s never lifted his trucks because he didn’t want the tailgate (his workbench) to get up too high. But some of the work areas are a bit of a challenge with a stock-height truck. Cory loves the smooth ride of the Chevy and was adamant that he wouldn’t give that up. But after talking to Jesse at Mulitia Muffler in Fort St. John, British Columbia, Canada, the idea of using a Kelderman Manufacturing air-ride suspension in the back started to look appealing. Jesse made a call to Kelderman and found out the company was just finishing up a kit that was exactly what Cory needed.

Cory likes to work on his own truck, so he installed the Kelderman kit himself, along with a BDS front lift kit. Now when he rolls up to a job, he simply dumps the air out of the rear suspension and the tailgate height is just right for comfortable working. The air-ride makes converting his truck from a work rig into a weekend pleasure cruiser very easy, too. All the welding equipment and tools are located on a skid on the bed of the truck. Cory fabricated legs for the skid, which he plugs in when he wants to remove the work stuff. After putting the legs in, he dumps the air out of the rear suspension and simply drives the truck away. In less than a minute, Cory can unload the 4,000-pound skid. Then it’s ready for all manner of toys and other items of fun.
The front bumper was fabricated by Cory himself, mostly for good looks, but it also serves as protection against the wildlife he often finds lurking on the highways. The 32-inch LED lightbar and HID headlights are there for the same purpose.

Future plans include an H&S Mini Maxx, a cold-air intake, and a 5-inch straight pipe exhaust. We’re pretty sure he won’t stop there, though. Or maybe he’ll start all over again with a new truck. Cory is a bit of a perfectionist, and there’s no doubt he’ll think of a few more items that he just has to have to make work and play better for him.

A Kelderman air-ride rear suspension setup makes Cory’s life a lot easier. Not only does the truck ride super smooth, but he can lower the truck when he’s on the jobsite for better access to his equipment.
