Last weekend I was working on my trailer and decided to do a video "walk around" of it. It's rather long as I tend to ramble -- about 20 minutes -- but hopefully it will give others some ideas.

After the updates and mods completed last weekend, I took her out for a couple days. She definitely performed better than last year. I'm pretty happy with the current state, though I do have a couple more comments.
In the video, I mention going with smaller tires. But I think I'll wait until I replace the springs and raise it an inch or two. Although ground clearance under the axle is not a problem, I don't want the hitch to go any lower. When you're articulating over major obstacles, you don't want the hitch going down into the dirt.
The pic below is from Grizzly Lake (Colorado). To get here, you have to go over some large obstacles, rock steps, and boulder fields. I didn't have any trouble with the standard ball hitch, but it is a bit noisy. I'd like to replace it with a 3-axis hitch as others have shown earlier in this thread.
The other thing I need to figure out is how to carry eggs. Although the ice chest and other gear stayed put, the contents inside the ice chest jostled around, and all my eggs broke. Imagine lifting your trailer about a foot off the ground and dropping it a dozen times. I need to work on that one.
In any case, this is a journey. The great thing about these trailers is there are always options and improvements to be made.
