Im late responding. Still am wondering about all this.
Hitch is a Class V now. So, 2,400 lb on the tongue and 17,000 weight trailer limit.
As a start, try and answer some of these questions and I may be able to add more.
1. How do you know when you have achieved proper WD for your truck?
I compare the height unloaded, then with the trailer on. I look at either bumper height or the helper springs on truck or both.
2. What year, make and model truck is it?
98 Ram 2500
3. What is the loaded TW of your camper?
wish I knew…
4. How many pounds of cargo are in the truck bed aft of the rear axle when you are trying to adjust the WD hitch?
Lots, 800-1000
5. Are you pulling hard on the pipe or lever snapping up the WD brackets?
yes, if trailer not jacked then I have an extra bar to make a longer lever, this is safer for handling the bar, but , yes, lots more force. That the stock lever is so small is of concern that I am doing this. Note: 30,000-40,000 miles of towing on bad roads so far with this…
6. What is the rating of your WD bars and hitch head assembly?
bought used, no idea. receiver is a solid square, not a tube.
7. What year/model camper?
1997 hilo, 4200 lbs
If we know those items, then I can ask about some for dimensions of the camper and rear overhang on your truck and give an estimated load the WD bars will be providing.
Hope this helps
John
