I was there a few years ago doing almost what you're doing. We weren't supposed to go on convoys at night, so we didn't have the prob you're having.
Just wondering if you're at Arifjan, thats where I was. Thats the place to be if you've gotta be there.
915, huh? A2 or A3? We ran 818's. Piece of crap but loved the desert heat.
Yeah, I don't really have any help other than to use the warranty. They say weatherproof for land or sea, use the companies money.
