I think of my trailer as another implement so I put this here. Anyways, I got tired of moving the spare back and forth between the trailer and truck and made a holder for it today. I had the mount from a boat trailer for some time, just wasn't sure where to put it. At the show, I saw one on a trailer and thought that would be a great place for it. So I got the trailer up close to where the welder would reach and proceeded to attach it.
First off, I welded a piece of 2X3X1/4 angle onto the top and bottom rail butted into one of the vertical angles. The mount didn't have a stud sticking out, so I used a spare FF stud welded into it. I took 2 short pieces of 1X1 tube to set the tire on to align with the stud. Got it all welded on real solid and now have a great spare tire holder for the trailer.
Here is the mount and the vertical angle on the trailer.
And here's more pics after the surgery was complete.
