Diana LeBlanc-Link from PPL Motorhomes joins the Wingman to chat about the importance of this one maintenance practice (that many RVers either overlook or procrastinate about). Overlooking or failing to do this one maintenance item is the single most costly mistake an RVer can make. Post your thoughts and comments below. If we read them on a future show, we may send you a prize. Thanks for being a part of our RVing community!
