I parked here 2 nights with the truck drivers on the Whiskey Pete's side. No propane in Primm April 2017. I ended up out here while I was trying to get propane in Vegas and got sucked into the rush hour traffic vortex and just wanted to get out of Vegas!
A lot of the trucks do keep their engines rumbling. I call it "sleeping with beasts". I would have no problem heading back there and venturing inside. I usually try to, but I wasn't feeling well.
