tongue weight & truck load

I have a '63 trotter. My equalizer bars are 1000 pounders, much too stiff of course. So I am looking for different bars. I don't know if I need 500's or 750's. The tongue weight of the trailer is 390 lbs. My questions: is the weight of load in the truck figured into the tongue weight? If so how? What do you guys think, 500's or 750's? Where can I find just the bars?

I would say you need 500's, but you didn't say how much load you intend to carry in the truck, nor what the capacity of the truck is. Whatever bars you get, you shouldn't overload the truck and expect the hitch to carry the load. You also did not say what brand of hitch you have, and that would determine where you get the bars. There are several places on line where you can buy hitch parts.

You are right about factoring in the TV when calculating Torsion bar selection.

It is much easier to transfer weight forward on a soft sprung, short wheel base vehicle compared to a stiff sprung, long wheel based vehicle.

Stuff in the truck is not counted as tongue weight. If you put 500# in the bed of the truck it doesn't change what the trailer or tongue weighs, but does effect GCVW.

You only need 500 lb. bars for a GT. You might find them cheaper on Craigslist or put a want ad here. I have not seen many on ebay but occasionally some show up cheap at swap meets at rallies.

I have a reese hitch. Looks like I need to find the 500's. I have looked about, but nothing yet. I bought another 1000 pounder at an auction the other day for $6. So I would be interested in trading. So the search is one.
Thanks folks
Chick

Chick,

Weight in the truck bed should be counted in selection of the weight bars.

The WD hitch bars redistribute weight from the rear axle to the trailer axle and the front axle of the truck. It's only a matter of geometry and moment arms.

The best method for selecting the spring bars is to weigh the axles of the truck and trailer, and select bars that redistribute the weight so the front and rear axles of the tow vehicle are equally loaded.

If you do this with the truck empty, and then add 500 lbs of gear to the truck bed, you will find that weight in the back of the truck does have a significant effect on the spring bar selection.

You do need to make sure that the added weight doesn't cause you to exceed either the GVWR, the GCWR, or the individual axle load limits of your vehicle. Usually the GVWR of the tow vehicle is the first limit you will reach.

The 500# bars are NLA, but you may be able to find a pair at a swap meet/flea market/rv dealer that has them from a trade-in.
