I replied to your other thread, but, to be more involved, what are you looking for and what are you towing with? Do you know your ready to travel vehicle weight to determine available payload? The ones you listed are 7600 GVWR trailers, average travel weight roughly 6700-7000 pounds depending on what is carried and how much water is in it. So given 7K, 13% tongue weight plus hitch, you should have 1050 pounds of TV payload, then those trailers will tow well.
I was really impressed with Cherokee Alpha Wolf, and they have a 23 RD that matches the floor plans you are looking at, in the same weight rating too. The Coleman series is pretty good, the one we have has been trouble free, though quality of materials, or I should say low quality is quite apparent in some areas, specifically the plastic trim that was cut short in many areas and particle board is now exposed. From looking at all the different brands, they all seem to use the same cabinetry, but the fixtures do vary quite a bit and that is what I liked about the Cherokee, the lights and other hardware were high quality.
