Please help me make up my mind...what truck?

[Madbomber88]

Ok guys, I realize this forum is highly biased, but I need some sound advice. I am in the need for a pickup. I already own a 71 K5 CST that I have partially restored and I love the style and and everything about it. I bought a house and am in need of a 3/4 ton 4x4 pickup for trips back and forth to to Mecca (Home Depot) hauling lumber and everything else.

I've got about $6000 to work with. Should I buy a later model 2500, like 84-87, or maybe even an early to mid 90s?

Or should I buy a 67-72 K20?

Advantages of the first option as I see it are:
- More reliable
- More fuel efficient
- Can get fuel injected models
- Smoother ride, more comfortable

Advantages of the latter are:
- More stout (axles)
- More available manuals (I really prefer a SM 465)
- Inexpensive parts and simple to work on
- Great styling and a much cooler ride

What would you all do? I want something that is as reliable as a daily driver, and allows me to do lots of work along the way. I want something that is well mannered on the highway and back roads. What is a fair price to expect to pay?

Looking forward to the replies! The pic is of one I have in mind.
