About Marvin
RVTI Level 4 Master Certified
Meet Marvin Kennedy
I created DIY RV Tech to help RV owners understand, inspect, and maintain their RVs with more confidence.
I am an RVTI Level 4 Master Certified RV Technician and author of The RV Owner's Preventive Maintenance Guide. My goal is to make RV maintenance easier to understand for owners who want practical guidance, not confusing technical jargon.
