MJ, how the h$%$ did the tube leak? Bring the freekin tube back and get another. Worth a shot so u can fish.
I hear ya with junk trailers. The first year with my Venture, I hit a small pothole and one of the spring shackles flipped over and put the tire though the fender!
Dealer didn't want to hear it!
Fixed them cheezy u-bolt spring hangers with a welder.
