With a little planning this is a DIY project. I remember meeting you at the Dogwoods rally at ft. boonesboro - I would say that your quite capable of this job.
I replaced the one on my other trailer a few years ago. Took a couple of hours.
Search the forum for other ac threads for hints on how to do this.
