Host Kevin Tetz installs new correctly-rated Goodyear Marathon tires for the 27-foot, 5,000-pound Airstream--which are installed on beautiful aluminum wheels. The RV Doctor, Gary Bunzer, joins Kevin to demonstrate the Airstream's waste system and install an electric dump valve. Electrical Engineer Jeff McCoy from Parallax Power Systems joins Kevin to install a new power converter, which converts AC 120 volt power to DC 12 volts when the coach is hooked up to city power. And finally, RV Maintenance instructor Terry Cooper from the Texas State Technical College RV division helps Kevin install a new "deep cycle" battery and complete some electrical projects.
