Nowadays, with my age and back. I jack it up high and buy those old 50's metal office chairs with arms and roll all over the place. They are Steelcase brand and came with those old steelcase desks. Find them on your local craigslist for cheap ($25). Comfortable, tilting backs and rugged. Jack up your vehicle, jack stands on high and sit up straight!! I made a "pillow" out of foam covered with a T shirt for when I go under the truck. Saves the neck. Here is another tip boys. When you start your project, take off those darn doors. They are always in your way. This way when you roll around you don't bump into them, when you come out from under you don't bump your head and working inside is sooooooo much easier. Full access. It is also much easier to restore the door stuff and window stuff with the doors laying on a table. I use my body dolly I made, covered it with a carpet top. Beautiful roll around, BIG, work top for restoring various parts.
