So nice to have the extra space

    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.

    Very Big!

      This is a very large and good looking box. Super stoked to use it this weekend. We've already thrown 4 North Face Base camp duffel bags, a portal crib and 6 folding chairs in it and it fits no problem. Looks like we won't have to worry about everything not fitting ever again!

      Perfect Size

        I debated between this box and the 1800 thinking all that I would need to transport are my skis. Since purchasing I have had no regrets, being able to use this for many other uses, camping, vacations, moving etc. It frequently saves me from having to take 2 cars on trips making it more than worth the fuel economy that is sacrificed, 2-3 mpg on either of my cars, Subaru and a sedan.

        Hi eka3075988,

        I checked with Thule and found that the Thule Atlantis 2100 XT Cargo Box will work with your Toyota Rav4 2010. If you have factory crossbars, it will work with those straight up. If you have a plain roof, then you will need the Thule Crossroad Railing Foot Pack with the 50 inch Thule Load Bar Pair.
