I don't have an answer to your question but I do have a funny/scary story for you about my cross country trek towing my first sailboat (a Cal 20) which started out in Fairplay, CO, not far from you. I bought the boat in Frisco and learned to sail her on Lake Dillon. I only sailed there for a year and decided to move to Minneapolis and slip the boat on Lake Superior. I knew very little about boats and trailers at the time and thought that since it made it over Hoosier Pass that it was plenty road worthy. WRONG. I made it to within 5 miles of Bailey when the leaf spring broke. I was towing it with a 30 ft. moving van and couldn't see nor feel a thing back there. Thankfully, my buddy was following me in my truck and we had walkie-talkies. He yelled to me to pull over because sparks were flying all over the place. We thought we'd just blown a tire so we tried jacking the thing up with the jack that came with my truck (personal, not rental) but it was not near big enough. We left the moving van and boat precariously on the edge of the road in search of a bigger jack. The hardware store in Bailey had a high lift jack so within 20 minutes, we were back at the boat ready to pull the tire and find someone to fix it. Just as the wheel left the ground while jacking it up, it became obvious what the real problem was, the leaf spring was broken in half. We removed the parts and threw the wheel in my truck and headed out in search of a fix. We ended up in Denver waiting for a custom leaf spring to be made. We dropped the broken spring off and the guy said come back at 11 the next day for the new one. SWEET! Only 17 hours lost. We were back at 11 and on the road back toward Bailey by 11:30. Had the tire fixed on the way and everything back in place by 2:30pm.
Now we were making progress toward Minneapolis...until we hit the ramp going from I-70 to I-76, moving at 60mph. That's when I heard my buddy scraming over the radio to pull over! There was barely enough room to get out of the way of the traffic, and no room to open the drivers side door without it being ripped off from the cars flying by. I got out the passenger side and got back to the boat when my jaw dropped to the ground. The tongue completely sheared off leaving the coupler still attached to the ball and the rest of the tongue dragging on the ground. The only thing keeping us together was the seriously undersized chain. I was dumbfounded that I didn't kill someone or destroy the boat. To make a long story short, my buddy found a phonebook and tore out the mobile welders page and within 45 minutes, had a guy on site adding a ton of metal to the tongue to beef it up. An hour and a half after the "incident" we were back on our way. We made it to Minneapolis the next morning without any more trauma. I still think we were lucky that it didn't happen in the middle of Nebraska somewhere where help could have been hours away.
