Do your research. Search the internet for the name of who you get your RV information from. What are their credentials? Who do they work with in the RV industry? What is their background? There is a lot of inaccurate and "copied without permission" information on the internet. Just because someone is an RVer or maybe sold RVs for a couple of months does not qualify them to teach technical subjects.

Your Instructor:
Mark Polk has been an RVer for the majority of his life, has a very extensive background in the RV industry and is highly respected. He began at age 15, washing RVs at a dealership in North Central Pennsylvania. It wasn't long before he was working as an apprentice RV technician under the guidance of the RV service manager. Mark put his RV career temporarily on hold to enter and serve a full career as a ‎Maintenance Warrant Officer in the United States Army. He completed airborne training and served with some of the most elite U,S. Army Airborne units, including Service Company 7th Special Forces Group (Airborne), 82nd Signal Battalion, 82nd Airborne Division and the 16th Military Police Brigade, XVIII Airborne Corps. He managed large fleet maintenance operations, where he not only had ‎to understand vehicle maintenance, he had to teach young soldiers how to maintain and operate ‎expensive vehicles and equipment. These soldiers came to him from very different backgrounds, and their prior experience with heavy equipment and mechanical skills were similarly varied. Mark had to learn how to ‎communicate with all of them clearly, concisely, and effectively, and he found that he had a ‎talent for teaching. The Army agreed, and eventually he was asked to produce written ‎instructional materials, including driver training manuals and operating procedures for motor ‎pools.‎

When he retired from the Army in 1996, Mark went to work for an RV dealership in ‎sales and service. He talked to customers about their needs and desires and helped them select ‎the right RV for them. He inspected used RVs for trade-in, he serviced customer RVs, and he ‎educated customers on how to operate and enjoy their vehicles. As an RV owner himself, throughout the years, he has owned and used all the classifications of RVs (travel trailer, motorhome, pop up, 5th wheel and truck camper). He even restored, from the ground up, a 67 Yellowstone travel trailer. It was clear to him there ‎were limited resources available to RV owners who wanted to learn more about how to operate and maintain their RVs. Owners’ manuals provide limited information, and most consumers ‎find them confusing.

Anecdotal information learned around campfires from other RV owners is ‎incomplete and can be unreliable.

Mark realized he had the knowledge and teaching ability ‎to fill that gap, and so in 1999, he began writing articles and books about how to choose, buy, ‎maintain, repair, and operate a variety of RVs. To date, he has produced more than 500 educational ‎videos, and authored 15 e-books, 3 paperback books, and more than 1,600 articles educating millions of RVers. His best-selling book, titled The RV Book, has sold over 52,000 copies to date.

‎Mark's first priority is the safety of his audience. To Mark, ‎this means anticipating the risks and challenges RVers will encounter when following his ‎instructions, ensuring that the information he provides is complete and accurate, and providing ‎enough information so his audience can make informed decisions about when to tackle ‎maintenance tasks themselves and when to take their vehicles to professionals.

His second ‎priority is his audience’ empowerment. He sends his students out on the road with confidence that they are equipped, prepared, ‎informed, and ready to enjoy themselves.‎Producing material that achieves those goals is a very difficult thing to do. RVs come in ‎a bewildering variety of different types, makes, models, and vintages, and when Mark writes ‎about tasks such as winterizing an RV plumbing system, (as we know there are many ways to winterize an RV), his instructions need to walk his readers through the process ‎regardless of which RV the reader happens to own.

Like his soldiers, his RV students come to him ‎with widely disparate levels of expertise, experience, talent, and motivation, and his instructions ‎must speak to all of them. Mark’s writing and video presentations are accurate and comprehensive. It is also clear, ‎concise, and easy to understand. He breaks complex, intimidating tasks down to easy steps.
