Super lite thoughts
We don't have that exact model, ours is the 8528 RKWS (rear kitchen). We picked it because of the lower pin weight. Basically, they're the same, just different floor plans.
The super-lites tow well and the revolution hitch performs as advertised. I think it would tow even better if the axles were about 18" further back, but then that would increase my pin weight.
The fit and finish is good, although my roof membrane had to be replaced after a few months. It was pulling back from the front seam. Replaced under warranty without issue, other than one small leak that I fixed myself.
When picking the unit up, we found that the ducting for one side of the AC was not completely bored through the roofing styrofoam. The dealer chiseled it out to make it deliver air to both duct banks.
The freezer door on the Dometic refrigerator had to be replaced as it was warped when molded, so it wouldn't seal well, causing it to frost over along the top front.
The other quality issue I've had directly related to FR happened during assembly where a screw partially penetrated the power wiring that feeds the lighting in the slide out. It was ok for a while, but eventually shorted the positive and negative wires, causing fuses to blow. It was past the one-year warranty, but I had purchased an extended 3rd party warranty which was described as a bumper to bumper when I bought it, but as you could guess, it didn't cover it. Be very leery of the 3rd party warranties. FR ended up saying they would pay for half.
So, I say all of those things to encourage you to buy FR's extended factory warranty. It may sound like I should be disappointed in the unit, but I'm actually not. We've made 11 trips in 17 months since we've bought it, pulled 6400 miles, as we tend to get away from the local area quite a bit.
