Aaron, What part of the Country are you in?
If you're going to part it out it might be helpful if we knew.
I for one have a cargo trailer I want to outfit for a Bike Hauler/ Camper.
I could use some kitchen and windows and stuff.
If you are going to strip it for just the engine then yea, I'd probably sawzall the floor out around the engine and remove it that way.
There is no way I would go through the trouble I went through for the engine if I wasn't going to use it again. Saving the wiring harness is probably not going to be a big priority if the Dodge Truck has one that will work still. We're not talking fuel injectioin computer controlled engines are we.
Keep posting up pictures, I'm always interested on how things come apart.
My Wife says I'm better at taking things apart than putting them back together.
