You need to measure at the fenders. Front fender should be back to stock height when the camper is hooked up. For me , it worked best to have my ball height 1" above the campers hitch height. Then to get the lift I needed I tipped he hitch head back creating more lift or transfer of weight onto the front wheels. The camper should also be level within a 1" or 1-1/2". I measured at the front n rear of the camper for this.
In the end my trucks front fenders are at stock height, rear has a 1" or so of sag and my camper is within 1- 1/4" of level.

Measuring at the draw bar gives you skewed measurements....you need to measure at the fender wells inline with the axle. As the back end of the truck goes down, and if the front of the truck raises, the receiver hitch will go down much further than the fender at the rear axle.

Getting the trailer level has to do with the ball height, not the load on the spring bars.....though the spring bars will affect the trailer attitude to a certain extent. Once the spring bars are set-up properly, then the ball height may need to be adjusted (lowered ?). After that, then spring bars may need to be adjusted again. It takes several adjustments of both to get things right. Many owners start with the trailer low in front, knowing that when the spring bars are added, the front of the trailer will come up some.

IMHO, not saying that Timbrens might also be needed, but correctly setting up the WDH should be the priority. Timbrens may be needed if the truck still sags after the WDH is setup correcty. If Timbrens are added after the initial setup, then the WDH may need to be readjusted because of the rear of the truck being raised......it is an almost endless cycle.

So if I understand this correctly the spring bar tension is determined by using the sag or drop of the truck suspension. Once you have this set as desired (.5" to 0"or 1/2 way to level are the 2 mentioned in the thread) you adjust the trailer to level or slightly nose down using the hitch hieght.

WOW...this is way more complicated than I realized! I think I will wait until I decide whether or not to get the new trailer then tackle this with the new rig and new spring bars or my current trailer...either way it needs some TLC. I will set it up with the timbrens since they are on the truck.

The spring bar tension is determined by how much weight you get distributed to the front end of the tow vehicle. The front axle weight should be near the weight of the front axle weight without the trailer hooked up. Mine runs about 60 lbs. over the weight with the trailer not hooked up.

Partly. The bar tension is mostly affected by the tilt of the head. Get the height right, then adjust the tilt to get the tension on the bars. It's easier than it seems.

So, what about the length of the chains?

Yes that also affects the weight distributing for those WDHs that have chains. Many WDHs require that the spring bars be parallel to the tongue frame, others not so much. The head assembly tilt would be the main adjustment to get the bars positioned to the manufacturers requirements.

AquaMan can take over here......I gotta get some errands done.

Thanks, you have been a lot of help.

There are some very informative videos posted at etrailer.com on setting up different brands of WDHs as well as some general WDH info.
