First, what difference nice weather makes to an old guys attitude. Two weeks ago minus 30C with wind, not much fun to work in a shop around freezing. Today +14C, no wind and the overhead door open.
All paneling, trim and mouse s.... is out. Windows are out of the doors and the doors are off too. Next on my list are all the floor covers I can or have to remove before I can think of removing the cab.
The box floor boards have to come off first, too. I like to keep track of where they came from and number them for making new boards when the time is ready for this job.
After the floor boards, I will remove all fenders, unbolt all box parts and so on.
