Keith...I don't know what your welding capabilities are, but check out some of Andrews materials/ strengths and weights in the design library, .120 and .090 2x square tube is readily available as well as 16 gauge which is what I welded up the last one with. Look around at what some of the manufactured trailers are using for tongues...my opinion...3/16, in a 2x3 profile is pretty beefy...could easily use a lighter gauge without sacrificing any strength, based on what you are building...and when it is all said and done...it's just that much more weight you are pulling, and having to stop. The body is going to provide a lot of strength, not like a piece of equipment riding on it and relying on the frame...you might want to drop Andrew (resident engineer) a PM for his thoughts...just an idea Doug
RichAFix...the frame as shown in the tutorial weighed in at 290# complete, 4'6" x 10 with a 4' tongue, rear jacks, tongue wheel, tires/wheels the works, and it has 15's on it.
