My wife, Carolyn, and I completed the RV Driving School with Lorrin Walsh. I have the highest praise and respect for the experience we had. My wife had virtually no experience towing or backing a trailer and my experience was what I got from the dealer (not bad) and teaching myself. My wife was dreading the experience, but came away smiling and feeling competent and confident in her ability to safely tow and back our trailer. I leaned tips and techniques that I wish I’d known five years ago when we bought the trailer. Lorrin’s lesson plans were obviously well thought out and well executed. He exposed us to most all the driving and cornering situations we can expect to encounter. 
In my view I think anyone who is going to tow a trailer should take a course like this.
