As I was pulling it home with my wife following me, she called and told me there was smoke or maybe dust "puffing" out of the drivers side of the trailer. I couldn't see any thing. so after about 25 miles and repeated calling from my wife I pulled over to check.
When I felt the brake drums on the drivers side they where too hot to touch while the passenger side was cool to touch. I immediately called the dealer to let them know. after about an hour they called me back and we together decided the best action was to return slowly.
The service tech took it out on a test run and decided they need to look it over and will get back to me ... that was yesterday as of yet they don't know. Was suppose to be sent to a major trailer repair center.
