I will usually give the customer the choice. He usually makes the decision on weather to ship it to the shop or not. I will make most repairs at the customer as long as they have the space and equipment to do the job safely and correctly. I don't let the time be a factor only because if you take a truck to the shop the customer will usually look for a "loaner" truck and if repair is done there then they get to see what it takes to do the job.
