About the author, Eric

I have been a hands on DIY'er since childhood, yeah since childhood with the idea that the job has to get done. My job (not a career) history is not the typical job history. I have run successful multi-million dollar companies, I have started RV related businesses from ground up. Over the years I have acquired many skills, some self taught and taught by others in a hands on environment. Today everything I have learned over the decades has come together and now I love to help others and keep myself involved in my favorite industry, Recreational Vehicles! This is not even close to being finished......
