Nope, you won't find it either. All you can do is pre-determine your own price range and then start looking at units within that price range. Narrow that to the floor plans and then the brands and / or models that interest you the most. Then compare the fine features, like aluminum frame vs wood frame, particle board floors vs plywood floors (if such exists), real wood cabinets vs particle board covered with wood simulated wallpaper, stand alone furniture vs built in furniture, queen beds vs king beds, double bunks, outside kitchens, even tires and the size of propane tanks on the campers, seamless windows vs framed windows, vs thermal pane windows, and insulation... fiberglass batting vs styrofoam. Does the camper advertise with a "winter package" or an "all season" or "4 season" camper? All of these determine, not only personal preference, but cost also.
Overall, in a very general way, if the camper comes with stand alone furniture, it's generally a higher end camper. (but not always).
So, basically, you need to determine what you are willing to pay, and then figure out which camper gives you the most bang-for-your-buck.
Remember something very important here: Every camper will have some kind of warranty issue. And every camper demands constant attention to detail to prevent things from falling apart. Every camper will need some kind of work done on it, if you can do it yourself, or if you have to take it somewhere, they are can never be neglected if you want them to last. You will forever be tinkering with it.
