Check for coolant leak near oil filter. I had a leak for several months on my 2006 and I would get low coolant every couple of months. Added less that a quart each time and the light would go out. Found a drop of coolant that would hand on and above the oil filter. Never enough to drip onto drive way. Was told it was a cooler leak. Supposedly it was where it bolted to the engine and there was a replacement gasket. Could have been the cooler itself that did not have a replacement gasket.

No known problems with that truck and especially with what your son wants it for. Obviously, you do not know for sure what kind of maintenance the truck actually had etc but lack of usually can be seen somewhat.

Our ordered new in 2004, built in March, 2004.5 CC LB 4X4 Chevy D/A is getting close to 170K and never had anything other than tires and one set of front brake pads needing repair, replacement or be fixed except for 2 replacing 2 burned light 1157 bulbs and one headlight bulb over the last 11 years. Just normal oil, air, and filter changes. Truck is still very tight with no rattles and not one speck of rust and we live in Michigan where they salt the roads in winter. His perspective truck has all 2 sided galvanized exterior body panels including the bed and box. 2005 was the exact same truck and D/A drivetrain as our 2004.5. Our truck has only been used for towing our Carriage Carrilite 5th wheel (12,840 lbs scale weighed loaded to travel) or tour TT or our 11'4" Lance TC as we have other vehicles we use when not RV'ing. Never overheated eith even when climbing to over 10,000 feet in the west in the hot summer towing the 5th wheel. A very small percentage ever claimed or reported overheating but some bashers like to spread the BS thick to make it sound like the sky is falling. The fix was cheap and easy even for those who did have or claim overheating.

Certainly not going to sell or part with ours as why would we? Drives & handles like new, and still looks new inside and out plus gets great fuel economy as it's before all the pollution stuff was mandated, very quiet running, and tons of power. Outstanding truck and many reports of them having 1,000,000+ miles on them now with the same engine and Allison tranny without any engine repairs or rebuilds done! What more could you ask for?

I forgot to mention that it really isn't for towing, but it might on rare occasions. It's really just a work truck for him, but I appreciate the heads up.

I never had any overheat issues in 160K miles of use with my dw 3500. Sold it 2 years ago. That is not to say it did not happen. As noted, probably fixable as my 96 6.5td overheat issues were to, with newer year parts.

Only thing I wished for, was 4.10 gears and the 6 sp auto. But the 4.10 gears were not an option, nor are they today!. I do not need 3.73 gears with a .81 od for the amount of driving I do on the freeway at 60 mph be it towing or empty.
