Awesome. Thanks for the tip and all the previous posts on your Thule. I'm handing the trailer down to my son, so I'm implementing several of your mods to make a better trailer for him.
Just for reference, I placed an order with Autoflex-Knott, Inc for a spare wheel/tire for my Thule Adventure 1700 trailer. I wanted to share the contact info for anyone trying to find parts for their trailer. I'm not sure if they can get any part, but wheels they can definitely handle.
