A quick rundown on a sliding 5th wheel?

What kind of trailer do you pull? If it's just a van or reefer, and you haul standard frieght... Set it where you need to be inorder to axle out legal at max gross... Then NEVER move it.

 

Its rather simple. If you want to add weight to your steers slide if forward. Put weight on your drives, move it backwards. Once you set it to where it needs to be you should not have to slide it. General rule of thumb is just forward of the center in the tandems

 

Different trailer setups.

Put in a position for 12,500 on the steers. Full tanks and leave it if you're pulling the same trailer.

 

Then you leave the fifth wheel where it is and you slide the tandems as you need to according to how you're loaded and the weight, etcetera.

 

Correct. I was assuming the OP already had that part figured out.

 

Get a beer load or close as you can to max. Make sure you 100% full of fuel too. Once your loaded scale and adjust your slider. Get close to 12k as possible and don't go over. You won't have to set it again really... if it's thats close your prbly running half fuel tanks at that point anyway. I personally use 1 notch forward of center and max my loads around 46k. Main rule is don't proceed overweight or under fueled. That 1000 lbs don't matter if your fueling every 300 miles. Shippers are responsible for letting you leave legal period. Go back and get things reworked if you have to. After a while you should know just by your pull and how much tire sag you have.. still scale bit you'll know your over. 1 notch is about 600 or so depending on the truck and load
