Looking good! A receiver hitch on the back might come in handy someday too. If I were going to put one back there I'd tie it to the crossmember that the hitch ends on. That way it's pulling from the ball and not the back crossmember.
I am planning on it was going to run the tongue all the way back but not enough clearance between it and the axel . I want to drill the pin hole before I mount it and it will go to the second cross member just like the front
Great. I'd still tie those crossmembers together in some way. You'd have room if you welded some tubing in between them. One reason I like the idea of the hitch on the back is I can't remember how many times I've needed to pull someone out or put a light pull on something but the trailer was in the way. With a receiver on the back end you could pull something, not a heavy pull but maybe enough to do the job. I love watching these trailer builds!
Looks like you framed out your fenders and then bent a piece of plate to go over the framed out fenders. The angles of your plate so it is linned up with the framed out section is perfect. Did you shear the plate and make the plate bends in your garage or take it to a shop for that to happen?
Nice work. Are you going to fill the sides, front and bottom with plate? If so, what gauge or thickness?
