Chassis Battery Bank Service and Replacement for NEWMAR BAY STAR (Gas Class A) I was bent over the battery compartment with a multimeter when I heard it — that grinding, labored crank, like the starter was fighting through mud.

Roof Seal and Skylight Maintenance for AIRSTREAM INTERSTATE 19X Most Interstate 19X owners assume that a roof seal is something you check once and forget about — that Airstream’s composite cap and factory Dicor application will hold for the life of the van if you don’t actively abuse it.

Electrical Inverter and Shore Power Integration Service for AIRSTREAM INTERSTATE 19X I was elbow-deep in the lower driver-side cabinet of a 19X I’d just picked up when the owner casually mentioned, “Yeah, it won’t charge from shore power anymore, but the batteries still work fine.” That sentence told me everything: the Xantrex Freedom XC 2000W … Read more
