I have an older Sunline Truck camper (85) that has worked out unbelievably for me, and I tow a H16 behind it. Mine has a shower, toilet, fridge, stove, and sleeps 4. It also is a hardside, so it doesn't pop up. We didn't want to have to deal with drying the canvas when it rained, or possible leaks. It also is a lot warmer in cooler weather.

The big concern is getting one suited to the size of your truck. If you have a half ton truck, then a pop-up is probably what you can handle. You can also check out sunlite (http://www.sunvalleyinc.com/trucks.htm), or Travel-lite (http://www.travellitecampers.com/index.html)for other lightweight campers. My camper weighs 2000 lbs, and I have it on a 3/4 ton truck. With a half ton, you are looking at something in the neighborhood of 1400 lbs. www.rv.net is also a good resource for researching truck campers.

Finally, to know the value of the camper you are looking at, you can check out the NADA guides. (www.nada.com) In addition, ebay has quite a few posted if you just search for truck campers. Good luck!
