The flashlight hack was almost by accident. I was trying to find a way to balance it and it just slid back, right into the perfect position. I still had to pull it out of there and either jam it up in between some wires on the left side (on floor facing up) of the ignition or try to hold it with my left hand. Just be forewarned, if you jam it up on the wires, it'll be great and awesome, until it falls out and wacks you on the forehead.
2 other comfort hacks I found were 1) a middle row seat from a Ford Expedition is the perfect height to lay on. If you had one of those adjustable height tables popular for engine removals, I'd use one of those to lay on. 2) a #4 soccer ball donated by the neighbor's kid works perfect as a head rest. It fits right in the curve of your neck, below your skull. Also, don't quote me on the #4 thing. I don't know soccer or soccer balls, but I do know hacks
