Of course installing a Premier Power Welder has been one of the most fun upgrades. I love to weld on the trail, as we showed in “Welding on the Run” (May ’10). Not to mention it doubles as a mobile welding unit in the backyard when dragging the big box to the back isn’t needed. I even use the 120V DC outlet to grind metal, blend drinks, and light up the work area while on the trail. We also fired it up for the welding shootout in our Apr. ’11 issue.
