That's a nice setup. Glad it's holding up for you. I was a little wary at the 10.4K. I've seen plenty of people complaining that by the time you get to 10K, your frame should be full box, and theirs is just heavier channel. But I figured I just bought it to give myself a little more buffer over the 7K.
I was warned about the lip on the edge of the trailers, and the the location of the wheels. So far... both have already proven to be an issue. The Chevy I mentioned has wide wheels on it, and the front tires... they rub a little. The deck width is 82", and it looks like it's 81.5" from sidewall bulge to sidewall bulge.
The wheels being back so far has its advantages and disadvantages. The sales guy made the point to me (I know, I know
...) that the wheel location wasn't such a big deal if I was towing with a 3/4 or 1 ton. The tongue weight wouldn't matter (for what I
was towing). That it may be more of an issue for a 1/2 ton though. What I didn't
take into consideration is turning radius. I have to use my Jeep to move it around the driveway behind my house because the long bed truck just won't cut it sharp enough. All that being said, it does track really well, and feels stable enough.
I haven't decided if I regret it yet or not. Time will tell I suppose.
