I wouldn't fret it much.. I've got an older 13 Eco Max Tow with #1920 payload sticker, but it's a lot heavier truck with #7700 GVWR and #4050 rear GAWR.
Towing a #7000 TT and I have not taken it over any scales, but it tows fine and no issues otherwise that would cause me to think it's not a good combo..
In the end, it's all about how you setup the hitch and how it's loaded and how it just tows for you in general.
I load my truck and trailer heavy and don't worry about it at all.
Good luck! Mitch
