How many like their diesel squares?

[rs74]

I was a day late and a dollar short on this last truck I was looking at. I have found another one, an 84 GMC short bed C10 that needs a transmission. I really liked the 6.2 in my old K30. I had decided I would like to try to get another one for mileage purposes. I am hoping if I can get ahold of one that I can see 20+ mpg's. Does that seem possible in a C10?

I know alot of people don't like them for the lack of power but for what I would use it for I think it would be fine. I am not sure what kind of gears this truck has but does have a 700r4 behind it that needs replaced.

If I want power then I will have to wait until my 85 short bed is done or hop into my 454 K30. So for those of you who do have diesels what are your thoughts on them. The one that I did have I didn't get to put alot of miles on so I really don't have much to go on other than the fact that I did like it while I had it.
