First off, thanks so much for documenting your entire process on this build, even the mistakes. I just finished reading through the entire thread and came away with a ton of inspiration and learned a lot. Your camper looks fantastic, I'm hoping I can build something similar and this is a huge resource for me. I do have a couple questions, if you have some time I'd really appreciate your insight!
Over the years, have you had any issues with the aluminum extrusion frame? I've read in other places that the hardware tends to loosen from vibrations over time. Not sure if that was just hearsay, but I'm really interested to see if you've encountered any of that in practice.
I know there are different methods to connect the aluminum extrusions. Would you recommend one method or connector over the others?
I noticed they make extrusion with some sides flat (without the channel). Do you think it's a good idea to use these on sides that attach to the exterior panels or sides that seal? I'm just thinking it might be easier to get a seal or attach the 3m adhesive to flat pieces.
Thanks again for documenting this build!
