Roof rack cargo containers

Just put a Prinsu rack on and am now looking for a locking case to mount up there for a bit more storage. I've seen the various options for drilling through a Pelican/Harbor Freight/Plano gun case and mounting with through bolts. I'm looking for something that will be a little easier to attach/detach when full and which will still seal completely. Best I've found so far is the Pelican "Cargo Cases" (BX55S) with their roof mounting kit. Any other brands out there I should be looking at?

 

I believe the roam boxes are good for the prinsu rack

 

I didn't see any means to mount those to a roof rack (other than ratchet straps or drilling holes and using bolts).

 

I think pelican just came out with some specific for this.

 

I haven't seen any others that are specificly made to be mounted like those pelicans. Maybe retrofit some frontrunner boxes?

 

This guy found a great solution to mount boxes on and off fairly easily. Might be a good solution for you as well?

This is pretty much exactly what I am looking for.
