Question on fender clearance

Jun 22, 2013

Q: How much fifth wheel clearance do I need to install rear half-fenders or full fenders on my truck? — Lance Tupper, Saint Louis

A: Our rule of thumb is with the air-suspension dumped (deflated) you need 4.5-5 inches of clearance from top of tire to bottom of trailer. If you have this amount of clearance, you should be able to accommodate fenders without needing to raise the fifth wheel slide assembly. — Bryan “Bossman” Martin, 4 State Trucks

The heavy-haul/oversize trucking niche can be lucrative for owner-operators who know the ins and outs of the business. That doesn't come immediately, nor without significant challenges. Shown here is owner-operator Jason Chamberlain's 1985 Kenworth W900B, powered by a Big Cam Cummins with a 13-speed. He owns two trailers -- a 55-ton, three-axle XL Specialized RGN and a 2017 Benson three-axle, low-pro step deck.

High-dollar freight means high cost consideration: Heavy and oversize hauling

There is a lot of nuance to the heavy-haul/oversize trucking niche. Equipment is more expensive, insurance requirements are higher, permitting and pilot cars add operational costs and much more. Are the rates worth the hassle?
