We just bought a 2012 Thor Serrano 34M. Drive it from the coast in Calfornia to our home in Arizona. Had a pretty good trip, not too many yhings wrong. Had a check engine light a couple of times which cleared after shutting down and restarting. Trouble putting into Park at times and have it scheduled for adjustment next week. Hope to get it on the road in the next month for our shakedown camping.
