Chinook RV

Hi, I'm new to the forum. I have a 1996 Concourse side entry. I'm looking for a little extra storage…
The roof has mounting spots for a cargo box. Can someone share with me how the originals were mounted? Mounting feet, cross bars and cargo box sizes? Pics would be helpful.

Thanks,

Mine came with the mounted brakes, but no box. I just ordered a generic rack basket thing. I'll take some pics in a few days when I do the install. Might help you some.

Took longer than expected to install the ebay basket ($100), but it's done.
