Leave your links alone. You have restored almost all of your front axle weight which is the goal of the WDH. Your front axle is almost the same hitched and unhitched, and your rear axle has picked up 800 lbs hitched. Not sure why you don't think that is OK. 3300/3300 is just a coincidence.
I used that on mine and the calculated weight was 220 pounds less than the Sherline weight (1380 lbs).
If you still have the weigh slips, could you PM or email them to me? I’m curious where/how the tool is wrong and what I can do to improve it.

We have been on the coast of Oregon for several weeks. We have seen several weigh stations that are not active but the scales are on. You can drive on the scale and see the weight on the display. We have weighted the TV solo and again with the RV for free!
