Buying a new car/truck.

finally going to be able to go get my fathers truck out of his estate. The vehicle is 4 hours away and I will have to drive it back tomorrow. It hasn't been driven much since he passed in Feb 2020. I wonder what things I should look for possible issues for one sitting that long. Other than battery obviously.
Tires - cracking in the rubber and air pressure, especially if it hasn't moved since then.

Gas might be old, too. I'm not sure exactly how you handle that if there's a lot of fuel in the tank and it's been sitting for almost two years. The lower the amount in the tank is the better situation for you here. Use fresh gas if you can.
