I have a 2012 Chevy Express 4500 motorhome with 55,000 miles. First and last GM vehicle I'll ever own. In the last three years it hasn't started because: defective fuse box (too much voltage drop), bad fuel pump, bad starter, battery lasted 14 months and now bad crank relay.
Is there something causing all these electrical failures, or is it because it sits a lot or is it just typical GM?
