How can I scale 45900 LBS on van

Unless you specifically have your truck spec'ed with a 13k+ front end. Either way if you only need 12.5k then manufacturer spec will suffice.

 

I have volvo 670 and utility dry van box. I'm surprised that you weigh only 1000 lbs more with your reefer set up. I thought 3-4 k more at least.

 

I also run a Volvo 670... How big is your sleeper?... I have a 39 inch wide mattress.

 

I would not be able to tell, really. I did not even know there could be different sizes of 670s. It seems regular like all the Volvos 670 that Swifts and Knights used to have. It has no APU, I do carry chains and tanks are 250 gallons of combined capacity.

 

Right on time topic..thx OP

My Volvo's registration says tractor is UNLADEN weight is 16,800 lbs. I'm adding a 150gal tank (1,050lbs of fuel) to my tiny 150gal tanks.

Does it mean I can scale 80,000 - 16,800 (truck) - 1,050 (fuel) - 10,000 (trailer) = 52,150 ????

I find that hard to believe...

 

I know that the trucks my company gets are custom spec'ed a little, but not sure how much... My Volvo has a diesel bunk heater and small refrigerator, no apu. I've also noticed that I have a little shorter wheel base than some that I have parked beside. I have heard some of the other guys that I work with refer to our trucks as "3/4 trucks"... My 5th wheel is not adjustable and when hooked to a reefer there is barely enough room for me (skinny) to get between the reefer unit and the sleeper, if I need to open the reefer unit covers open all the way I either have to unhook or turn the tractor at a bit of an angle to the trailer to allow me to open 1 side all the way.

 

That should explain the small weight difference then. My catwalk gives me some room and I can slide the 5th wheel too. Interesting. I could only imagine that single drive axle trucks could weigh so much less or day cabs.

 

Yep that would be the difference... My company hauls a lot of bulk potatoes that pay by the 100 weight... So they probably spec their trucks to be a little lighter, so as to be able to put a little more weight on.
