I can't send a pic right now because the car is covered up but what I did was get one of those stainless water bottles with a Camelbak insulated sleeve/holder that has a loop on the side and I zip tied the loop on the holder to my roll bar down on the side of the drivers seat so that the bottle sits on the tunnel up against the roll bar. Works just like a holster - easy to get to and out of the way/secure
Here's the sleeve - remove the carabiner and then zip tie the sleeve to your roll bar down near the tunnel
