That depends on your skill, knowledge, patience, quality of equipment, and the quality of the replacement truck.
If you are highly skilled, know a lot, have a ton of patience and time, and have good equipment and a clean truck to part, it is easy. Beyond that, you need to think hard and make the best decisions you can. Don't be afraid to make a few boo-boo's along the way; that's part of the learning experience!
Other opinions should follwo shortly.
Good Luck!!!
