how is the rear sag with that weight? Did you order with the air suspension?
It's not too bad, I have roughly 400 lbs. tongue weight (mid engine car makes it hard to get more without backing it on). I don't put much payload in the trunk, as I add it to the frunk on the race car for more tongue weight.
I would always recommend air ride when towing with this new T1 trucks, but it requires max tow and 22" wheels at a minimum (so ~$3,500 total)...additionally with constraints, it makes it near impossible to find.
For my personal use, I didn't really miss it for the 6-8 weekends a year I tow. If I was doing a travel trailer or heavier loads, I would probably hold out for air ride/max tow.
