I have a 30” River Rat dry box for my Spider. I’m happy with it.

Beautiful job! After you cut the tubes how did you drill the holes for the LoPro attachment bolts? Thanks.

I’ve cut crossbars several times. I cut the vat then mount it on the boat having lined up the location of the LoPro hole. I start with a very small bit then progressively increase. The lLoPro hole acts as a guide. It’s not necessarily exact but it’s been successful so far.

Small update. Today was mildly productive, I installed:

2) Two sidebars in the captains bay

I’m interested how you like those side bags. I’ve seen them online and wondered how much they end up holding.
