How to Build a 5'x10' Utility Trailer
I needed a trailer to haul around a snowmobile so I decided that I might get*better use out of a general utility trailer instead of a snowmobile trailer.* I checked the local trailer retailers and found that the going rate for a 5' x 10' utility trailer was around $1,300 Cdn.* The trailers weren't very*strong and were made mostly from light angle iron.* Always looking for a good project, I decided to build one instead.
Good webpage, even includes AutoCAD plans. However, I'm sure our guys could do (or already have done) the same project for less money.
