About
My name is David Sizemore. I am a Certified NRVTAA Technician and a Certified NRVIA Inspector. We have been an RV family since 2013, and our class A RV travels have taken us from Alaska all the way down to Florida! We are currently stationed with the Air Force in Southern Georgia where I provide onsite RV service to the surrounding GA and Florida areas. Additionally, I also offer virtual support to anyone who just needs a little technical advice and help troubleshooting when they feel they don’t quite need a mobile tech onsite.
I have been supporting customers across many forms of home care for 45 years. I have a Bachelor’s Degree in Business Management and experience working professionally in Real Estate, Landscaping, Horticulture, Small Engines, and Pest Control.
In my free time I enjoy landscaping and gardening with my beautiful wife, Debbie. I also enjoy woodworking and traveling as our schedule permits. We have four children, two of whom are also military affiliated, and a daughter whose family is a fulltime RV military family.
We hope to support you in your RV adventures and provide a little peace of mind in your new RV purchases, RV maintenance and care, and general community kindness and understanding!

He came in a good time frame. He analyzed my water heater and a couple of small issues. He then came in a reasonable time frame and replaced it. I am very happy.

David helped us out with a pre-purchase inspection on a Class C. He did an extremely thorough job and his report gave us confidence that we were not buying a lemon. He is a super nice guy, and a very patient and proactive communicator. I would not hesitate to reach out to him again!
