"You can add a 'crew cab' to your pickup without spending thousands of dollars for a new vehicle with our new add-on kit," says Bill Katehis, president, Horizon Coach, Inc., Riverside, Calif.

The kit consists of a one-piece fiberglass cab that bolts onto the pickup box using four bolts. The cab has a carpeted interior with fiberglass storage cabinets on each side that double as seats and a walk-in rear door with two big windows on back.

If your pickup has a sliding window on back you simply open it up to access the add-on cab. If it doesn't have a sliding window you just remove the pickup's rear window. A watertight seal connects the two cabs together.

The cab comes with a false floor that can be raised to make a bed. The cab can be painted to match the color of your pickup. Options include sliding or pop-out windows (with screens) on the sides and "vista" windows on top. Brake lights are also available.

The company also offers bolt-on fiber-glass sleepers that mount behind the cab. The sleeper's carpeted floor is even with the sides of the pickup, leaving about 30 in. of space under the sleeper for storage. Sliding or pop-out side windows are available.

"Both the crew cab and sleeper leave plenty of room to hook up a gooseneck trailer," notes Katehis.
