Look at the atvsuperstore. They have 3 or 4 boxes for o utlanders. I do think they're in the $350-400 range though too.
Check out this thread it was a pretty good discussion on options.Hi All
I have a 2015 Outty 650 max xt. Looking for a hard box for the back. Just hard to spend 430 on the can am box. Any help would be great Thanks
I used the same pelican cases as Billavista. $100 each on amazon. Then mounted some rotopax to them.Want waterproof/dustproof, get Pelican, yes they are expensive but the only case I know of that is truly water/dust proof. Billavista posted how he mounted his here.
