Otto Friends have called me Hank LOL but they know where to come for propane advice,domestic and vehicle use !! Hank Hill could have a new lease on life if he would do episodes on truck motor fuel propane. It took me 10 years to get a pal to try LPG on his s-10 now he just runs the wheels off of it like I do. I watch full time for propane vehicle accidents and if you follow the guidelines it is safer than gasoline. Those tanks are made to stand a crash,and mostly once the dust settles the fire fighters will get it out of the ditch and throw it in the truck bed with the propane still in it.
