Well, I towed the trailer home today with the Andersen. I can say one thing with absolute certainty- this TT has nowhere near the tongue weight that my fiberglass Weekend Warrior FS3000 30' front sleeper toyhauler had. My truck hardly dropped an inch when I set the tongue down on it. I don't think I have it set up just right yet, as I did seem to feel some wind buffet at highway speeds , but bear in mind it has been 5+ years since I've towed anything this size.
I don't think this trailer is over 1000 tongue. I plan to go to scales in the next few days to get some empty weights.
