THE RIG: 2006 GMC 5500 built out by Imperial Industries.


COMPANY: P & C Sanitation, Seymour, Wis., was started in 2005 by Paul and Connie Marks and maintains 400 portable restrooms serving construction and special event customers.

SPECS: Owner Paul Marks bought the ’06 GMC chassis in 2008 from Fox Valley Trucks, then had it built out by Imperial with a 575-gallon waste/300-gallon freshwater steel tank and Masport HXL4 vacuum pump and a Burks DC10 water pump. The 19,500-pound GVW truck is powered by a 325-hp Duramax diesel engine tied to an Allison automatic transmission. Features include a dual restroom carrier on the back, aluminum wheels, two aluminum storage boxes, spray-on bedliner on the hose rack and work lights.

SHOWING MY COLORS: On this unit, Marks stuck with the red cab that came with the truck, and had Imperial add the tank in white. Maverick Graphics added checkerboard graphics and lettering in a clean look. “Everything we’ve got has a checkered flag,’’ Marks explains. “It dresses it up a little bit and offers something to break up the white tank. When you back into somebody’s yard, you can’t be driving junk,’’ he says of the need to update trucks frequently.

WORKIN’ FOR A LIVIN’: Kevin Marks runs the GMC truck on daily restroom routes heading up to 90 miles north from the company’s headquarters, while Paul Marks runs another truck on routes up to 60 miles south of the office. The company has maintained a good clientele in construction, and serves a variety of special events, mainly in the summer months.

ROLLING THE ODOMETER: The GMC logs about 40,000 miles per year.

WHAT I LIKE MOST ABOUT MY TRUCK: “It’s just sharp and clean. Kevin takes nice care of it. You take that truck through a parade and everybody’s looking at it,’’ Marks says.

CREATURE COMFORTS: The rig came with all the extras you’ll find in a pickup truck: air conditioning, cruise, tilt, CD player, tinted windows and an air-ride seat.

WHY GMC: It’s all in the Duramax diesel, Marks says. “One of the guys that rents from me is a mechanic, and he knows the Duramax inside out. If I have any problems, he takes care of it.’’ One of Marks’ several businesses is operating a truck- and tractor-pulling track, and he appreciates a truck that knows how to pull. He says the majority of trucks that show up for pulls run Duramax engines, and the GMC easily pulls his 16-place restroom hauler or his 6,000-pound home-built restroom trailer. “That truck plays with it. It doesn’t even know (the trailers) are back there,’’ he says.

PAMPERING MY RIG: Marks delivers the props to his brother, Kevin, for keeping the GMC in showroom condition. Kevin Marks greases the truck every week, washes it four times a week and details it once a week. The engine is meticulously maintained, with oil changes every 5,000 miles. The vacuum pump is flushed with diesel every couple weeks. Tires are rotated regularly. The truck is kept in a heated garage to minimize wear and tear from Wisconsin winters. “For the year of that truck, it looks brand new. Kevin does all of that. He’s pretty particular about that truck,’’ Marks says. “As much as those trucks cost, you have to take care of them. If the trucks look nice, customers think they’re getting quality service. If you’re backing up there with junk, they’re thinking they should have hired someone else.’’

MY BACKUP SERVICE VEHICLE: A 2005 Ford F-550 with the same tank and pump package as the GMC, also from Imperial Industries. The backup is Marks’ daily driver, with 183,000 miles on the odometer.

WHEN I’M NOT IN THE CAB: Paul Marks spends free time with his wife, Connie, and their two sons, Konor, 7, and Kyler, 4. He also enjoys deer hunting, ice fishing, snowmobiling and competing in tractor and truck pulls.
