There are pros and cons to both, that is why it is best to have your trusted mechanic go over it first.

Check the tires condition
Tires, tires, tires… I know I always find the time to speak about tires. Why? Well because they are one of most important part of the flatbed truck. Or any truck actually! But they can also tell you a lot about the truck and the operator’s driving habits.
Are they worn or showing signs of uneven wear? The rim does it show signs of hitting the curb a few too many times? Are the rims showing hidden signs that the rotor or the brakes are going bad?
Much like you can tell a lot about a person by their hands, the same is true with the tires.
Check the engine
The engine is the other most important factor. If you check the oil and it smells burned that is a bad sign. If it is too thick or too thin that too can be a bad sign and possible symptoms of a greater issue. Perhaps the rods are bad or the gaskets leak.
Also when you start it, does it turn over properly? How do the spark plugs look? Check the filters. Even remove the radiator cap check and smell it, if has a burned smell that is not good, possibly a sign of other hidden issues. So look closer and let the mechanic you have with you do what he is paid for!
