Too many numbers

I have been searching, googling, reading a bunch and went from totally ignorant to totally ignorant and totally confused! Looking to adjust my weight distribution hitch for better towing. Was going to start by visiting the scale to get some numbers to ensure I have the correct hitch. Assuming I do have the correct hitch I am wanting to set it up correctly.

Question for the scale. I was going to weigh with my current dealer set up.
Front TV axle
Back axle
Total vehicle
Then tongue only

Then weigh again with wdh on a tighter chain link setting
Front TV axle
Back axle

I want to verify my GVRC, ABC, and XYZ numbers jive with the recommendations.
Then I want to continue to try to find an owners manual or info online on how to properly set up the hitch to maximize my TV to tow my trailer.

Does any of this look accurate or am I still way off?

Yep- those are essentially the numbers that you want to get. On the scales, you likely can't weigh the "tongue only". You get that by a little math.

When weighing a TT, you do 3 weightings:
1) Truck and trailer with WDH engaged
2) Truck and trailer with WDH bars in the truck bed
3) Truck only with the WDH bars with the trailer

Great info and links. This subject is confusing me too. I don't have any issues towing my trailer (that I know of) but want to make sure I am not to heavy or light anywhere for sure.

I should have close to everything loaded that I will typically be carrying in a couple weeks. Then off to the local Blue Beacon for a wash and weigh.

Does the Blue Beacon have sectioned scales like CAT scales ?? If so, make sure each truck axle are on separate sections, and both trailer axles (together) are on another section. This should give you good readings.

I think all CAT scales have sectioned platforms.....you should be good to go.

Ok so I did some measurements and visited the scale. I am sure this has been hashed out before but looking for any advice at all.

Tow Vehicle unloaded

Hitch 19.5"
Front 21.5" reference to top of fender
Rear 22" reference to top of fender

Loaded no WD hitch

Hitch 16"
Front 22"
Rear 20"

4 links on the WD hitch
Hitch 17"
Front 20 3/4"
Rear WD 20 1/4"

5 links
Hitch 18"
Front 20 1/2"
Rear 20 1/2"

Weights

4 links on the chain
Front 3240lbs
Rear 8620lbs

5 links on the chain
Front 3320lbs
Rear 8600lbs

Truck and trailer
Total 16040

Truck only
7140

Trailer only
8900

Tongue only
1140

In looking at the numbers above I am seeing that I need to be on the 5th link correct?


My torsion bars are rated at 1000lbs. So my first step I guess is to upgrade to ones with a higher rating. I neglected to measure the front and rear trailer heights so I will do that after I get new bars so I can work on the hitch set up.

Seems like you're dropping the front end quite a bit. First things first....replace the bars then do it again (the adjustment, not the weight). At almost 200 lbs. over the bar rating, they're probably bending too much. I'm willing to bet that, with bars rated at between 1000 - 1400, the rear won't squat near as much with the same number of links and you'll actually have to back off on the tension to bring the front back up.
