Cletis is probably right. It does depend some on location to. Around my parts that truck would bring around 2500. In the end its what its worth to you.
As mentioned, these projects take time. Have a plan. You can tear them apart and stack it in the corner in one day. I spent approx. 6 years on each of my two projects and found that if I did something every day it kept me motivated....hence my saying of "at least 15 minutes a day". Its nice to fix a few things as you take them off. Some stuff is just plain labor. Remove, clean, prime/paint and put it on the shelf for when you need it.
Its not motivational to look at a pile of pieces everyday.
Good luck, keep us posted. My opinion...YOU CAN DO IT.
