GAWR= Gross Axle Weight Rating. Meaning, if you were to weigh the trailer the axles shouldn't have more than 6400 lbs each, or 13,800 total. They would never have that much anyway, as 14000 lbs trailer has roughly 2500 lbs pin weight. That would put 11500 on the axles and 2500 on the truck. I really can only guess what the trailer weighs, but I'd say between 4500-5000 lbs dry.

Gross axle weight rating. The max amount of weight each axle can carry.

So single tires must be rated for at least 3,200 pounds each.

And two axles could carry a max of 12,800 pounds. So they assume hitch weight of 1,200 pounds to come up with the GVWR.

But hitch weight on a properly-loaded and balanced gooseneck trailer will be about 18 to 20 percent. So when you were grossing 14k on the trailer, you have a hitch weight of around 2,500 to 2,800 pounds. Subtracting that hitch weight from the GVWR means that you'd never come very close to overloading the trailer axles as long as you never exceeded the GVWR of the trailer. /ubbthreads/images/graemlins/cool.gif

Some trailers set the GVWR as the total of the GAWRs, ignoring hitch weight altogether. I guess they don't want any problems with blow outs. /ubbthreads/images/graemlins/shrug.gif

85 14 bolt 10 1/2 weight ?

I have a restored 85 GMC C3500 with a 14 bolt 10 1/2 inch Corporate "American Axle" rated at 8,900 pds, I have purchased a 38 ft 3 axle Fifth wheel RV Trailer with a total weight of 9,999 pds!

Will be pulling it from D.C. to Houston, Tx!

Can it pull it considering that all axles have been fully rebuilt, bearings, seals, brakes, new tires "Dually", pinion/diff rebuild????

GAWR indicated the weight an axle can bear, not what it can pull. For example, my 2005 SRW f350 can support 7000lbs on the rear axle, but it can pull a 140 tonne train car if it has enough traction.

Pretty sure someone already did it.
