Let me see if I can do this from memory (odds aren't good 😀
You want 3 weights - do them in whatever order makes the most sense to you - for me, I started with C (below), then B then A. And be in the vehicle every time. I screwed that up and Ron G was able to (accurately) guess my weight after I posted the tickets 😀
(A) is for just your tow vehicle. You'll get a steer (front) and drive (rear) axle weight.
(B) is with the trailer attached but NO weight distribution. With my ProPride, I approximated that by loosening the WD jacks until the bars swung freely (sort of like when you unhitch). What you see here is how much weight you're lifting off the steer axle of your tow vehicle and how much weight you're pushing down on the drive axle just by connecting the trailer.
(C) is with the trailer connected and WD applied. My suggestion for this one is that you start with the jacks at 6". By that, I mean measure from the top of the a-frame to the bottom of the sleeve that rises when you apply WD. Here you're looking to see how much weight you've removed from the drive axle and restored to the steer axle and trailer axles. If your steer axle needs more, raise the WD jacks another half to full inch and test again. If you need less, lower them and test again. Most recommend 100% restoration (i.e., if you lift 500# off the steer axle, you want to push 500# back to it). Your owners manual will tell you what to do. In some cases, 50% is all you need (or in this example, 250#). Mine wants 50% but I find a better ride at 90-100% restoration.
Do those 3 measures, post your tickets here and you'll get lots of advice on what it means and what adjustments might be needed. Good luck!
