5th Wheel Placement

You could just try it sometime you can just take on things yourself.Or just leave it all the way back it looks cooler there

 

Notice with the 5th wheel all the way back, the kingpin sits exactly between the drives. Any further back is dangerous. Though I’ve seen quite a few custom set ups for special situations. On mine there’s no middle of the slide. Closet to the middle is 1 extra adjustment slot visible in front or behind the 5th wheel riser brackets. I prefer 1 less slot visible in front. Just a little bit forward of center. Puts a little extra weight towards the steer. Long wb Truck. Depending on wb, location of tanks, being able to scale out at 80k with an evenly loaded trailer is most important. Once it’s set at the best spot, you can almost always make it legal by putting the rear of tandems, or mudflaps even with the rear of the load. Leaving 6-8ft open at rear of trailer helps. The rest falls into place. Avoids ever needing to move the 5th wheel again.

 

On the back and you can't pack as much weight.

The perfect setting is loaded with full tanks and the steers about 12,750. Most trucks burn off about 2.25 steer pounds to 1 drive pound. Depending on fuel tank location.

Oregon says they'll radio highway patrol if your steers are too light.

I don't know what they consider too light and it's been a few years. Don't know if that thinking still plays out in that state.
