I say buy what you like and thats in any hobby. From truck or car collecting to collecting salt shakers. In the end you are the one that needs to be happy dont buy something because you think someone else thinks its cool or its more valuable in the long run. Unless thats your goal I think most of us here really enjoy our trucks for the main reason they look cool and remind us of the past. Around this part of the country it doesnt make much difference sellingwise whether a 47-55 is a 5 or 3 window but there is a difference between 55-66 big and small windows. Most want and will pay more for a big window.
