I tow a 28ft (bumper to tongue total length 25ft box) tracer air 250 trailer. It is very light but weighs in at 6200 pounds gross weight and I pull with full water tank most of the time. I live in Idaho and all our camping is in the mountains. 2 adults and 3 kids in the truck, crammed with firewood and all manner of camping gear, my 17 expy EL pulls it like it's not even back there. Even in the mountains, it's mind bogglingly fantastic.
I use a husky centerline TS wdh and have zero sag when properly hitched up with my 800-1000 pound bars. My tongue weight is right at 930 pounds with full water tank as measured by my DIY tongue weight scale (thanks YouTube). I too would like a slightly larger trailer as my kids get bigger but don't like the thought of adding 1200 pounds and 3ft more to do it. I don't think the rear suspension could take any more, the advertised dry tongue weight of my trailer is 498 pounds, yet in practice is 930. I don't know how anyone tows anything heavier if tongue weights are that different from dry numbers (I. E. Trailer I looked at last weekend said 620 pounds dry tongue weight, but probably 1k wet!)
