Question for CAT 3406 Guru/Mechanic

It has a PTO/Wetline. If you stare hard at the pics, you can see the mounts for the hydraulic tank on the frame rail just behind the passenger side fuel tank. Also, you can see the hydraulic tank sitting in the back of the pick-up truck parked on the passenger side of the truck.

I can only assume the fuel tanks are where they are to make room for the hydraulic tank...

The truck has tons of potential and is "mostly" complete. I told the current owner, I'd only feel safe buying this as my first truck if it was brought to a shop and gone through with a fine-tooth comb.

I don't have the time to complete even the simplest services. Fluid and filter changes from bumper to mudflaps. Hoses, belts, grease, brake check, etc...
The truck has been sitting for a few years and it shows...

The current owner had the engine/trans/rears done not many miles ago, and I'm told, all still have 1 year left on the purchased extended warranty.

Considering the asking price of the truck, I'm sure it's an as-is deal.

Just for reference, what would YOU pay for a truck like this if the owner had paperwork proving that the engine/trans/rears only had 32,000 miles on them?

 

The current owner is a friend+co-worker I've known for just over 3 years. And we'll continue to be friends+co-workers after the purchase.

The truck's been sitting because (as you can see) she owns a Peterbilt. She thought the truck was sold, but ended up getting the truck back when no money ended up changing hands...

 

The other truck is an 07 Pete. Which one would you sell? But back when the Freightliner was her only truck, she'd do whatever it took to keep it on the road.
