should i move my fifth wheel?

200 pounds difference is not the wag problem, check the tire pressures. Also make sure there is not a crack in the trailer suspension. Yet sometimes it is the road you are on.

 

Not to be rude, but why would you ask this question? Perfect weight distribution.

 

Think on it. If you move the tandems back 3-4 holes you'll add that weight to the drives and (minimally) to the steers. You're as close to perfect as you can get now; no need to fight it. Get rolling.

By "wag" do you mean trailer overhang? Why do you want more weight on the drives?

 

Trucking is very much an imperfect thing... leave it alone and roll with it. Or, to follow my granny's advice when making dough, "roll it out once and don't #### with it."

 

Are you crazy? Why do any of that when you're already perfectly balanced? I don't know, maybe you just like moving your axle weights around. The numbers you posted are the numbers I try for.

 

Looking at my truck driving book the load as it is, legal. Under 80000 lbs. Drive axel (check) not sure about the bridge weight, Trailer axel possibly good.

• W = the overall gross weight on any group of two or more consecutive axles to the nearest 500 pounds.
• L = the distance in feet between the outer axles of any group of two or more consecutive axles.
• N = the number of axles in the group under consideration.

Federal law states that two or more consecutive axles may not exceed the weight computed by the Bridge Formula even though single axles, tandem axles, and gross vehicle weights are within legal limits. As a result, the axle group that includes the entire truck—sometimes called the "outer bridge" group—must comply with the Bridge Formula. Interior combinations of axles, such as the "tractor bridge" (axles 1, 2, and 3) and "trailer bridge" (axles 2, 3, 4, and 5) must also comply with weights computed by the Bridge Formula (see figure). More detailed information on the Bridge Formula is available at www.ops.fhwa.dot.gov/freight/publications/brdg_frm_wghts/index.htm.

 

@#19 --

I'm thinking the OP doesn't need to worry about the Bridge Formula. If he's pulling a 53-foot long tandem-axle trailer with a three-axle sleeper-cab tractor, he's about 73-73.5 feet long. He's good, he's not concentrating a lot of weight into a short distance. Honestly, pulling 53s and 48s and even doubles--often closer to 80k than the OP's load--I never had to deal with the Bridge Formula; the combinations were all too long and not heavy enough to run afoul of it. I never did heavy haul, though, or containers, or short trucks. The BF is about weight and distance.

They have an "=" instead of a "+" inside the brackets, but they offer a reasonable explanation anyway

With a load like the OP's, he'd probably only get into trouble if he had to slide the tandems farther back than the maximum KP setting for the shortest state he's going through to get his axle weights legal. Then it would be up to the shipper to take some off or redistribute the load.
