2006 Chevy Silverado 2500HD duramax diesel LBZ engine - $24,000 (Mount Gilead)

This was my dad's truck.
He bought it new.
I'm the second owner.
.
.
he would still have it but unfortunately he passed away so now it's mine.
I personally have sunk about $8k into it in repairs and parts to include all new glow plugs, brakes, front end rebuild, 5th wheel hitch frame rails, all new fuel lines and so on.
My dad (and me) took very good care of this engine and transmission.
It gets oil changes regularly whether it needs it or not.
Looking to sell this and one other car I own to consolidate into a new truck.
Otherwise we would keep this truck.
It starts every time.
Michelin tires with over half of the tread left.
Cd player, power windows, door locks, mirrors.
Camper in the picture is not for sale.
Comes with 5th wheel hitch rails installed in bed/frame of truck.
Roadmaster adjustable rear spring assist system installed on rear leaf springs.
Actual 5th wheel hitch not included.
Extended cab with suicide doors (4 door).
Text with questions.
Best offer gets him (we call him Eugene).
Thanks!
