3 hours, front clip removal. This is leaving it bolted together and having help lifting it off as an assembly. Rad, batts, front tires, grill and bumper off, various brick a brack attached to the inner feners. Wiring for headlights and stuff unplugs at the junction block, so it comes off with the clip. Total weight is about 150 lbs without hood.
8 remaining body bolts...could be 2 hours, could be worse.
E-brake
Steering shaft
tranny and T-case linkage
Hood release (should be when the front clip comes off)
Accelerator cable.
Engine side wiring (unplugs at junction block on firewall.
AC lines, heater hoses
Working rearward:
Fuel filler neck
Axle vent
Likely need to drop the gas tank anyways to get the rearmost body mounts.
I'd count on a day to take care of the above.
For body lift off I'd use an engine hoist at the rear of the truck to get it started, and when you have the room slide a 8-10 foot 4x4 through the wheelwell area. A second 4x4 just back of the firewall. I've seen steel drums as supports, but of course you could build whatever you needed.
I think a weekend would have it off and the chassis rolled out from under it.
