Used 2002, Chevy Silverado 2500, Red Plow/Cap/Tool Box for sale in Raymond, NH

2002, Chevy Silverado 2500, Red. Plow/Cap/Tool Box.
We know very little and have no experience mechanically with trucks.
We inherited this vehicle from a relative that purchased it to repair/fix to use in his small landscaping/plowing business, but wasn’t able to complete.

I will state/list what I know regarding its history and condition.

When running the engine and transmission/shifting appear strong.
Truck was used as a lot vehicle for most of its life.
The miles are low, odometer reads 151,000 +.

It won’t start without a strong jump or new battery.

This is what I was informed of;
Needs Transmission line (leaks).
Needs Hydraulic plow line/hose?

Body is fairly clean for it’s age.
Some small rust spots/holes on lower side panels.
Interior is fair/good, needs a wicked cleaning.
