1st I'm surprised they used 10% since the rule of thumb is 10-15%. 15% of 12,900# is 1935#.
You need to weight truck and trailer together and then weight just the truck to get our real numbers. You can't go on what it use to weight. Your WD hitch will also move so weight up onto the steer axle.
Normally the TW listed is dry weight. If you divide 1318# by 8692# = 15.16% ratio. Your gross of 12,900# times 15.16% gives an approximate 1956# TW at GVWR on trailer.
Spent about 45 minutes politely talking to the service mgr about that debate (10 vs 15%) and they always go only by the GVWR of the trailer when calculating tongue weight. Also discussed how a TH is generally heavier than a TT but ??? My truck is 7500# on the scale so with my loaded trailer axle of 11100 plus a tongue weight of about 2200# my GVWR is 13300# and the listed GVWR of trailer is 12900 (400# over).
I told him that I was under the assumption that the above link should be the dry tongue weight but he says no it's the loaded or GVWR.....Time to call Evergreen on Monday. - mdamerellExplorer1st I'm surprised they used 10% since the rule of thumb is 10-15%. 15% of 12,900# is 1935#.

I did loaded, minus half of my fresh water and had a tongue weight of 2300#. Dealer threw in a hitch when bought new with 1400# max TW bars and say they are calculating TW of 10% GVWR. 10% of my GVWR of 12900 is 1290 and I'm at 2300# with a trailer axle weight of 11140#. I know my truck is 3000# weighed at the rear axle unloaded so I did the math and subtracted the dead load and came up with about 2300#???? In the above link the dry weight of that trailer has a tongue weight of 10% of GVWR so is the tongue weight listed the dry weight? Confused?? - Y-GuyModeratorThe only way to know for sure is to take your rig to scales and weigh it.
