Sell truck?

Wife and I have been kicking around the idea of selling our truck, 2008 F150. The truck IS paid off and that fact alone really hinders my decision. Would be selling it to my parents and buying a '95ish F150 straight 6 then keeping the rest. The extra money would be great to supplement my lost hours at work while at school and I ride my bike every day anyways. Truck would just be used for hunting, fishing and working around the farm. What say you?
