Did you leave the Fleetwood Tioga/Jamboree off the list on purpose? Their big advantage is a small passthrough area in the basement storage that the others don't have. I don't think it's possible for somebody to tell you which is the best brand. If you made a list of all the features you'd find that each brand has some things that are better than all the others. Only you can decide which of these things are the most important to you. Problems: My unit had an embarrassingly high number of careless factory build mistakes. Fortunately the basic design is pretty good and with the initial problems ironed out it's a pretty solid rig. Personally, I'd eliminate any of the brands that are obviously inferior in my eyes, then go for the floorplan I like the best. The list of differences can get pretty huge, things like batteries, baggage doors, tanks and dumping hardware, fresh water fill, lighting, cabinets, furniture, etc., etc.
