I've just ordered and waiting for delivery of the Seahorse 720's for my bike. They are plenty big enough for touring alone, they lock which the Pelican's don't (pad locking the cases every time you stop will get to be a royal pain) and they are much less expensive. I'll be using Givi racks and Happy Trail's pucks to mount them, also on order.
Hopefully all the parts will be here next week. The pucks and the cases have been shipped, not heard about the racks yet. Figures, the racks have to go on first
Not to 'split hairs' but the Pelicans I got from Caribou DO have integral keyed locks on both the cases themselves as well as the racks. I'm amazed at the amount of stuff I can stuff into two 35L sidecases....they lock which the Pelican's don't (pad locking the cases every time you stop will get to be a royal pain)
I went this route also, except I didn't buy the pucks. Mine worked out fine on a long trip. I kind of wish they were a smidge bigger, but then again, I probably took some stuff I really didn't need. For the price of this set-up, it's hard to beat in my opinion. Yes, there probably are nicer set-ups no doubt if cost is not a factor, but these work for me. I recently crashed on dirt and other than gouges on the lid, the case and Givi rack seem to be fine.For me the $$ that Caribou wants for adding locks and making a rack is wildly excessive. I've got under $300 for the whole setup (Givi racks and Seahorse cases and Happy Trails pucks), about 3 times that price for the Caribous.
