Best used truck campers for ~4400lbs payload SRW 1T 8' F-350

I owned a wolf creek, it maxed out my 2006 Ram 3500 SRW but it was nice. Dealer did seal whole camper with geocell before he let me have it, I think may have seen water problems with them and this is his fix to keep his customers happy. But in the 2 years I owned it we had no problem with it. we traded it in on a AF990 after we moved up to a dually. I think he sold our Wolf creek in a week. I also would look at the other ones shown above, I seem to recall northern lights were a little heaver of those choices above.
