Rule of thumb is the title stays with the cab.
I guess some clarification of what you want to do. Are you going to use your regular cab as the "parts truck" and build up the crew cab, on the current crew cab frame? Or are you going to use the crew cab, cab and install it onto the regular cab frame with a really short bed? I think the big thing is, you will need the title for the cab that you plan on driving/plating. Not sure on the lost title taking "months".... here in Indiana, you apply for a duplicate title and you have it in less than a week...... if he is being a bit "odd" on the title, I would get the VIN and have a local LEO run it an make sure he isn't trying to dump a "hot truck" on you......
Some states may do an "assembled" title. They issue you a new VIN #..... but I think you have to prove where everything came from. Just like building a "trike" from a motorcycle and a VW Bug..... you have to prove where those parts came from.....
