The overall length of the deck is 8-0 with the square being 5-0 X 5-0. The springs came from a Mazda Sedan, not sure what model. It tows really well empty behind my Dodge 2500. The trailing arms are 3/4 X 4 inch flat bar and the bar grate decking add enough weight to keep it from bouncing around on uneven pavement.
It's a stout trailer and I am hoping someone can use it.
