Pictures of trucks with protective liners.

A pickup truck can carry over 5000 lbs of cargo. You can use it to carry firewood to your campsite. You will need about 10 logs for a decent fire that will last 2 hours.

A good solid model can carry a camper as shown on this page. I would recommend a full size PU for camping. You can also get a basic topper.

A truck bedliner will protect the metal from scraps and dings.

Full size models cost more, such as Tundra, F150.

For middle size: Nissan makes a midsize called Frontier. Toyota makes the Tocoma.
