Questions on Replacing Bed Wood?

[custom10nut]

I’m about to replace the original Bed Wood in my truck with new.
I want two prevent a rookie mistake.
Two questions I have:
1. Can I disassemble the bed by taking the metal strips off on at a time, without the sheet metal “collapsing” onto the frame?
2. Is it the “Washered” bolts drilled through the two bed boards that actually holds the bed off the frame?
A third related question is:
What would be the SAFEST way to lift the bed off the frame, in regards to preventing sheet metal damage.
My three options are:
Lift it off using my Two Post Lift. Where do I place the lift arms?
Lift it off using my engine hoist. What would be the lift points?
Lift it off using the Pallet Forks on my tractor. Again Lift points?
This is going to be a one man job, because my son is deployed overseas for the next year.
Also, how do I disconnect the bed wiring from the cab? Is there an electrical coupler? Or do I have to cut and splice it? (I know, I don’t want to do that)
Thanks in advance for any insight
