I was driving by Thousand Oaks MB a week or so ago and pulled off when I saw two pax conversions with SCA 152 pop tops. I asked the salesperson who the upfitter was (they only had a dealer price of about $13k for the top, which isn't too bad for a dealer) and he said some company in San Berdoo which I couldn't find on the MB Upfitter locator.We were there last Friday, there was only a Sportsmobile Metris. No GTRV, which was what I was hoping. There was another interesting Metris that was only available as a rental, and not retrofitted for camping. It had 4 captain's chairs in back (facing each other) and a table. Looked like a 4-rail system instead of the typical US 3-rail setup. Even though it was only a rental, it looked like Thousand Oaks Mercedes was the supplier of the Metris. Looking at their website showed a few interesting Metris that were converted for camping.
