Air is a must for me. I will say I enjoy my truck with the power windows and locks so I think I need those. The next truck will get remote start and keyless entry if it doesn't have it. Both my 96's have ok radios. I don't need much. The newer trucks have a computer screen which I don't need. I use navigation on my phone as well as all the features it is capable of. Oh and 4 wheel drive. The snow can get pretty deep here.
