We are borrowing a friends trailmanor and planning to tow with 2019 Highlander XLE. We have installed Redarc brake controller and tough tow WDH. BUT, we are still a bit worried about damaging new Highlander by towing TrailManor with too much tongue weight.
We decided to measure the tongue weight using the methods suggested at Curt.

First set of measurements using scale at local dump:
highlander w/o trailmanor attached 4940 lbs (2 highlander axles on scale)
highlander WITH trailmanor attached 5500 lbs (2 highlander axles on scale)
----------------------------------------------------------------
tongue weight 5500 - 4940 = 560 lbs
Then we removed 2 propane tanks (30lbs x 2 = 60lbs)
from the tip of the tongue and repeated measurement at local dump
highlander WITH trailmanor attached 5380 lbs (2 highlander axles on scale)
---------------------------------------------------------------------------------
new tongue weight is 5360 - 4040 = 440 lbs.
QUESTION IS: how is it possible to remove 60lbs and change tongue weight by 120 lbs = 560-440 ??
we also did the other method that CURT suggests with a bathroom scale and got pretty much the same result ??
Can anyone explain why ?? What the heck ?
total rig weight including us was 8460 on dump scale
TM only was 3520 on dump scale loaded with water, propane tanks, battery and spare tire
