Editors' picks: $20,000 used pickups are ready to work it out

Fall is here, and with the change of seasons comes autumnal yard cleanup and winter preparations. What could be a better assistant for such chores than a pickup in your driveway? Our editors have picked their secondhand favorites you can buy for just $20,000 -- well under half today's average transaction price for a new, full-size pickup. We used NADA Guide pricing data, assumed 12,000 miles per year and selected "Clean Retail" values to keep things fair.
