Generator Maintenance Learn how to keep your RV generator running smoothly. From "RV Roadtrips" episode DRVR-112

Wendy and Tim Metro rely heavily on their generator when dry camping. Since buying the RV back in August it's always worked great; however, they dread the day that it may fail on them while RVing in the middle of nowhere.

Host Gary Bunzer explains the importance assembling a spare-parts kit for their generator. He shows them what to put into the kit to help them make easy repairs in case the generator fails while on the road.

The Metros enjoy this Class A motorhome when they hit the road, but since they frequent desert climates it's vital that the batteries are maintained properly.

And Means Dry Lake, with the emphasis on "dry", is a destination where Tim and Wendy Metro, and their boys T.J. and Drake, love to dirt bike!
