Have you decided how to make curved custom extrusions for the corners? 3D printing maybe?
Crazy... sorry to hear of your trouble. Hope the shipping company steps up to assist with the costs and delays.
Ouch that sucks. I wonder how all the right hand drive imports come in? I guess they are well detailed in Japan for loading them up to come into Vancouver. Assumption that the guys bringing them in also learned this one the hard way by having one or two sent back.
Might be good to have the cleaning process and state of the vehicle documented before it goes into the shipping container this time. Present that to customs before it travels across the ocean again.
Over the last two weeks I talked with several importers and they all learned their lessons... They are all now paying big $$$$ to get them detailed before shipping.
My brother and my dad have brought in motorcycles and snowmobiles from the US to Canada. Not so bad there if they decline you entry, just turn around and find a pressure washer.
How will it delay your project? Did you have a set timeline you were working towards for a trip?
If you are looking for a thought diversion I have a question about your FRP panels and corner extrusions? Would they be suitable to make a Four Wheel Camper type pop up slide in clone? The base box and roof seem simple enough but can they be joined to support the cab over bed?
