Thanks Calvin!
The current owner is a bush pilot and he's got his A&P ticket, so he knows about maintenance. Difs serviced every 15k, tranny at 20k, etc. After speaking with him, I'm fairly certain that 5 he truck is up to muster. Still, I'd like to have someone with my best interests in mind take a look at it before I commit to buy. I'm considering calling a local diesel shop and inquiring if they or one of their mechanics would do a inspection next weekend. I'm also considering having the truck shipped to North Florida and flying down to pick it up and register it then driving back to NY. After fuel, food and lodging it'd probably be a $500-$600 difference and save me a bunch of time which these days is in short supply...
