Wow, gorgeous truck Triggerfish!

These guys pretty much covered it, although I would say I wouldn't be concerned over the miles vs age, these trucks aren't that fragile that it would be a huge factor.

Also, 24v's don't have the injector issues the Common Rails do; if a CR loses and injector, good chance of melting a piston and needing a rebuild (been there, done that), whereas a 24v or 12v loses an injector, you swap it and keep trucking.
