If you have the "Coleman" Mach Series, now sold by AirExcel or RVP/RV Products, that fan motor's about $100 on Amazon and a new capacitor about $10.
Common hand tools, wire nuts (or much better, crimp connectors) somebody to hand you the motor.
I wouldn't hesitate to put a new motor or things like capacitors in a 10-YOA Coleman Mach. Clean the coils while it's apart. You can see the Condenser Coil at the rear of the unit, and it pulls its air forward from the rear into the unit. So it's the "backside" you want to clean. The Evaporator can be seen with the sloped sheet metal "top" in front removed. Clean the squirrel cage interior blower wheel too. You need a long 3/16" allen wrench for the cage. Look carefully at the fins. The one different one is where the screw is.
