I borrowed an Atlantis 1800 and used it for a trip last year. The amount of space it helped us to save was great so I went ahead and bought one for ourselves. I went with the bigger one as I needed the space. Wow, it's big! I love the space it gives me and installation is definitely snap. The only reason why I gave it 4 stars is it seems a bit flimsy compared to the 1800. Perhaps this is because the size is bigger, I don't know. I wouldn't let it dissuade you from purchasing it if you need the room to transport your stuff.
