Thank you everyone for the input!

There was a Facebook post on one of the Teardrop DIY pages last week that had photos of a trailer with cracks where the tongue butted to the frame and if I recall, it had gussets underneath the corners.

Tony, I like your frame design. I have been reading through your build thread and will go that way if it's stronger. I am trying to get a better understanding of the forces at work on a trailer chassis. When you say "pull apart" are you meaning the tongue is trying to come out or the entire thing is trying to scissor? Either way, that's scary. Just for fun I mocked up a better model on Sketchup with a full length tongue. Now that I see it drawn though, it's probably overkill and too heavy. I'd be interested in where the weak points would be on this type of design.

What tubing dimensions did you use on your trailer?
