Oh boy here we go...
I'll assume you are talking new campers.
We just went through this exercise...after looking at a lot of campers and doing a lot of research, our list would include the following based on quality only (you will have to decide floorplans);Eagle Cap (which we did purchase), Arctic Fox, Adventurer.
Based on new campers, we quickly ruled some out based on the quality (lack?) of construction.
We did not look at Host as they are hard to come by in New England.Chalet did not have floorplans that work for us.So cannot comment on these 2 brands.
Lance is now using Azdel...nothing new there...others have been using it for years...
Good luck-LOOK at all the floorplans you are interested in person. The quality of construction becomes apparent after making comparisons. Take pics on your phone, make notes, etc
