Find out how long the truck has been sitting. Even new trucks for that matter. I was not really aware of the damages caused by not being operated steadily but have had to deal with them. -Injector O-rings...$500 -Air Compressor (today)....prob $800 Not really a lot of money but what can catch you off guard is the down time. Fortunitely, I have more then one truck. The other problems I have had: -Replaced King Pins...$500 -Replaced Tie Rod Ends...$200 -New tire, mount & balance...$250 Tow truck: $160 Don't get me wrong, I love my truck and I work my truck for every dollar it cost me. If you have a $30,000 budget and plan to buy a $30,000 truck....I would recommend a $28,000 truck. There's other things I can still do to it like new: -ABS Sensors -Radio ...but the truck is solid. The gaskets I can blame on sitting, the other is just the 'usual' stuff you could say. Personally it would be a lot of money but from the business end it is a small expense. Keep yourself a nest egg for anything you buy because you never know what little thing may happen when you don't want it to. International is a really good truck and I'll be buying another one soon enough. Once I've got a new Air Compressor on there I should be solid for the road ahead.
