Finally an update. What an adventure. It took the builder a little longer than quoted because of the non standard dimensions. He had to pick up an axle for a 4' wide bed. He made 2 mistakes. First, even though I showed him pictures and told him I wanted the entire thing framed so I can cover it, he left the roof braces off. No biggie really. He also built it the wrong size, but that ended up perfect actually. It ended up being a 4x8 bed instead of 4x6. The extra 2 feet does add some headroom and still looks good and makes it more useful.
So, I mounted the wheels/tires and took it for a drive to go get some lumber that was being offered to me for free. Well, mud-grip tires DO throw rocks into a rear windshield! As soon as I heard the crash I knew what happened. I was almost at the end of the dirt road. 10 seconds more and I would have been good. I was planning on installing fenders but got too excited about the free lumber. The window replacement quote was $420! Man, expensive free lumber. But wait! The next morning I was a "Pull-A-Part" when they opened at 8am and BAM! They had several rear windows for my suburban. $33 total! I got off easy. Lesson learned. I picked up fenders later that day.
I used 1x6 treated boards for the bed as opposed to plywood as the with was actually 50" so I would have had to piece it together. The plywood roof is just sitting on top for not but I will probably screw it down tomorrow. I am going camping this weekend and am going to use the trailer for extra gear (sleeping in my awning-room).
So the brief few times I have pulled it, I have really liked it! It is so nice with small amount of width it takes up on back country roads and not having to worry about driving so slow.
Well, life is getting in the way now and I have to focus time and money on a job change so it may be awhile before do much more with it. The next thing will be the aluminum siding but not sure how long it will be before I get around to that.
