and let this be a warning to you all: USE THE PARKING BRAKE! My yard is on a slight incline, and as I went to remove the rear driveline, prepping the truck for flat towing, she rolled down. Thankfully I was on my creeper, and I tell you I've never scooted that creeper so fast in my life! (I actually tried to pull the p-brake cable by hand, but as the truck gained momentum, I bailed.) 'Sfunny, as I ALWAYS set the damn brake ... the once I forget... doh.
