NRVIA Member Full Profile

Win Semmler


Tomahawk, WI, United States

RVIS, LLC is an RV inspection services company owned and operated by me and my wife, Joanne Semmler. I have received a significant amount of training with respect to all of the features and systems within today’s recreational vehicles and continue to allocate time to continuing education opportunities to keep current with a fast-changing industry. I am a certified National Recreational Vehicle Inspector’s Association (NRVIA) level II inspector and was affiliated with RV Inspection Connection, a national RV inspection organization.

I feel it is very important to continue expanding your knowledge of the business and industry you are involved in. I have taken several trips to RV manufacturers, as well as suppliers to the RV industry, to get a first-hand look at the various manufacturing processes used in the construction of an RV. I also go to as many RV shows as possible to see the new trends in floor plans, materials used, appliances, etc. being introduced to the market each year.

The knowledge I have developed of RV’s and their systems has allowed me to become a provider of walkthroughs for private customers and it has also allowed me to become the preferred provider of new owner walkthroughs for a local RV dealer.

I have been involved in several RV related webinars as a guest, and have also delivered a training webinar to other NRVIA inspectors. In addition, I have delivered training seminars at the annual NRVIA inspector conference, as well as the annual Workamper Rendezvous.

In April 2017 I was very honored to be chosen as the first-ever NRVIA Member of the Month.
