Load the truck like it was ready to pull the trailer and then weigh its front and drive axles separately.
Then load the trailer as it would be on a trip and hook it up the the truck. You can use a CAT scale that has a platform for the trucks front axle and separate platform for the trucks drive axle and a third platform for the trailers axles.
Simply subtract the two drive axle weights for a pin weight number. Don't exceed any of the truck or trailers axle numbers.
Question;
If so, how do you know before purchase if your truck can pull a given 5er?
By looking at the trucks GVWR and in particular its FAWR/RAWR numbers on the trucks certification placard on the drivers side door post.
The most important number from a safety standpoint is not exceeding trucks the RAWR as its carrying the pin weight. RAWR includes tires/wheels and the rear spring pack.
Now how much weight can a tired 20 year old truck pull (tow rating) ??
Good question but not knowing your trucks engine size/hp or tranny or rear axle ratio I sure wouldn't guess. Maybe someone has that year model truck and can help.
