Contrary to that I've read where it is strictly the weight of the trailer tongue. This would mean that my shank, hitch and ball would not count toward tongue weight. I've Googled and Googled and there is a lot of conflicting information.
Yeah, a lot of discussions about that subject matter. IMO (again, just my opinion) I don't believe that it's adding to the actual loaded tongue weight, but more the fact that the WD spring bars may be required to support a percentage (?) of the weight that was "added" to the rear of the TV's rear axle (not all the weight rear of the axle) .
Just supports the rationale that when we CAT scale weigh our TV's to do so under real "loaded" conditions, ready to camp.
I also "think" that the subject matter is focusing on any weight that is "added after" one's loaded TV/TT CAT scale weights and WDH adjustments have been preformed. So if your son's weight wasn't used in your initial CAT scale visits and WDH adjustments, then I could see because of the location of the added 135lbs may impact your WDH adjustments (thus the spring bars are supporting some percentage of the "added" weight).
Definitely a good campfire discussion!
