Buying my first truck DD15

Hello, I'm considering buying my first truck which is a 2013 Freightliner Cascadia DD15 with 500k on it. Asking $29,500. Planning on using the truck to haul bulk pneumatic tankers after I get a blower installed. The isle off delete seems to be a good sign as it could mean the truck hasn't spent much time idling.

Haven't run the vin# so not much is known about it. Test drive it this morning and everything ran nice and good I have pictures as well as around $6300 worth of work they've put into it. No leaks from what I could see. Gauge pics during cold start as well after an hour of running and a 50 mile drive.

 

cold just started.. Oil pressure high. after an hour of running, 50 mile drive and back to the shop idling. Seems awful low Oil pressure but I don't know much about this engine.

 

They've had it done already.

One thing I noticed is that the EGR actuator is moving every few seconds causing the engine to rev. Not sure if this is normal. Was less after warm up but still did it.

 

I'd like to find something with a 12.7l 60 series and a 13 speed. But gliders are expensive and a lot of older Columbia's around here I've seen have 1.3 million on them and worry they're too wore out. But I agree that older is better. Kinda hard for any emission system to cause problems when it don't exist on the engine.

 

I may end up passing on it. I have time on my side after all. Rather than spend $30k on a headache spend 40ish on something with a reman S60. Really want to do it right the first time.

 

I'm still thinking about it. Truck shifted like new "10sp ef" clutch was nice and grabby. Everything seemed to work and AC was cold enough to run me out. Sleeper looked like it's never been slept in. Curtains looked new and with a idle off and no apu I doubt it was slept in much.
