A little info please regarding '72 Chevys

[Cameraman]

I have come to the seat of knowledge for some information. I have a desire for another truck. My last one was stolen in '99 and since then have driven my wife's car. Over the holidays we visited her family in the middle-of-nowhere Texas where I saw a 1972 Chevy Cheyenne Super for sale. It looked to be in good shape and cost $5000. I loved the way it looked, and decided right there I wanted one. Here is my situation and my questions. This will be my only transportation, not some weekend cruiser. I need a long bed as my wife and I are remodeling our entire house and I need to carry 4'X8sheet stock and lumber. We are also landscaping (rocks and soil to be hauled.) I am not even close to being a mechanic and working on cars easily frustates me. I can change oil and plugs, but not much else.

Is an old truck for me? Will it be reliable? I am a nurse and have to be at work on time. I have read that the 67-72 trucks are collectable. Should I look at a later date to save money? Are parts readily available on something that old, and are they more expensive to have repaired than a newer truck. I want something stock that looks nice. What amount should I look at spending?

Thanks for any help you guys can give me. If there are any important factors I missed, please inform me.
