Got a new (used) 1991 isuzu Trooper in 2000. Finally, in late November 2006, bought a a new UNI-SOLAR panel (Model US-64 64W PV M) from Affordable Solar Group in Albuquerque, NM. Cost at that time was $319. (This was a higher than I expected to pay: the story was there was a shortage of panels in the market because the Japanese and Europeans were buying them up). They still show the panels on their site, but as of this writing (3/17/10) they've been discontinued: http://www.affordable-solar.com/unisolar.us64.64watt.solar.panel.htm

(Old) Refrigerator: Norcold 330, 3.5 Amps at 12 Volts.

This panel has some advantages over the old system. These glass-free panels are extremely durable. You could shoot a bullet through them and they would still work. Or be hit by a rock (a more likely scenario). They are good in high temperatures (like the desert), and are extremely shadow tolerant. They supposedly work well under various lighting conditions such as cloudy days, because of having different layers that absorb different frequencies. And they came pre-framed.

You can just make out the fridge in the photo below (same old Norcold 330D - takes a licking and keeps on ticking). I covered it with silver insulated mylar from a windshield shade to keep it cooler.

Took it for a "shakedown" cruise in the Anza Borrego desert starting March 5, 2007. Camped out in a little wash. Used the same Norcold fridge, which is amazingly sturdy and reliable. Replaced the old RV battery with a larger, higher capacity model.

Below is a closer view, showing the mounting brackets. I decided not to use a hinged mounting system this time, because I ended up keeping the old system flat, and it's vastly simpler. These are also very secure brakets: they mount underneath the panel, in a slot int he aluminum where you can't get to them, and on the roof of the vehicle, four bolts and silicone hold them down. You can also see the windbreak I put on the front. Without it, the panels make a curious low wooshing noise above about 20 mph speeds while driving. The windbreak is made from a piece of wood, but was later replaced with aluminum bar, bent around the sides.

Took apart the back where the condenser is. Vacuumed and cleaned out, including coils.
Checked functioning with A/C at 5, 4, 3 setttings using thermometer. Got down to around 20 degrees F.
Replaced rubber bumpers (they'd pretty much dissolved) on top that stop the lid when opened.

Replaced Norcold fridge (which was getting loud) with Dometic CF-25, which is narrower, higher, and more advanced electronics with some useful features. Replaced the old old charging system with a SunSaver 6, installed a wiring block, replaced battery.
