It took my Dad and I about 2 hours last night, and 2 hours this moring to get it done. We had some problems with batteries dying on us, so we installed two brand new ones, and a isolater. I think we were drawing too much power in the cab. There is a radio, amp, ham radio, and fog lights that were running off one battery. Well hope this fixed the problem.... If it ain't a Chevy, don't raise it up!
