I have a Progressive 9200 and I used their "Troubleshoot" sheet off their website which I highly recommend printing out and keeping in the trailer incase you might need it. Anyhow everything at the converter checked out fine.
The Excide was put in by either the Factory or Dealer so if you go by the tires then I'm sure the battery was the cheapest they could get.
I've gotten 2 1/2 years out of it so it won't break my heart to get rid of it and put something decent in it.
