Thanks, guys. I think all together my brother and I worked about 15 or so hours on it, but we did two trailers (that were identical). It's a lot like building a model. The easy part was building it, the part that took the longest was finishing it up (installing them, putting the little rubber band holders on, putting the locks on the bottoms and drilling the holes in the floors, etc. But, now that all is done, I'd say it's well worth it.
