Northern tool 5′ x 8′ trailer serves as the base for my teardrop trailer. It comes in two boxes and there was a extra fee to have the delivery driver to lower it off the freight truck. I highly recommend springing for this service as it would be extremely difficult to impossible depending on your resources.
In all it took about 4 and a half hours to assemble with the help of a couple friends. The trailer was exactly to spec (96″ x 60″). Make sure you don’t tighten the bolts all the way until the trailer is fully assembled as this allows you to make it as square as possible. Measure from corner to corner diagonally to ensure squareness.
