Ok, trailer is getting close. Going to finish it up today and start painting.
Just for reference, here's how the bike was packed for 2 up camping, just got home last night. There was nothing, except for a few tools, that didn't get used. Not much that can be trimmed from the load without degrading from the camping experience. Might be able to lose 5 pounds if I tried hard enough.
Here's about where the trailer is at now. It's a bit farther along than it looks, the lack of wheels makes it look like I just threw a box on some parts. Just need to bolt on the swivel hitch adapter, weld on a cooler mount for the tongue, paint, and come up with a plan to secure the box. I think a treated 2x4 would be the best solution, might help with lowering vibration and adding sound deadening somehow. Not sure what I'll use there yet, but it's time to figure it out.
