I think your trailer build was fantastic. I enjoyed the video of the entire process. As far as the Youtube clown that doesn't like it, he is entitled to his opinion. Having said that, he probably doesn't have the skill to build his own, so he would have to purchase a "cookie cutter" model. When you build your own, you know how it was built and what is inside of it. Having rebuilt an RV before, I was really disappointed in the lack of craftsmanship in the RV, and it was one of the "top of the line" models when it was built.
Having built many equipment trailers over the years, I know what hard work you put into that trailer, and I'm very impressed.
Great Job.
