I've got the Rockwood 2511S which is pretty much the same as the Flagstaff version. (Still made by Forest River).
I tow it with a 13 F150 and it does it well, but would not want to haul anymore with it.
I don't full time by any means, but I think I could with this rig. Everyone looks for something different in floor plans, and if the 25KS works for you, then I don't think you'll go wrong with it.
I only have 2 trips under my belt with my Rockwood, but so looking forward to 2020 camping season!
Good luck!
Mitch
