Earlier this year, at Lincoln Parish Park (Louisiana) I met a fellow who bought a new Extended Sprinter and did a custom conversion. According to himó and he seemed quite proud of itó by the time all was said and done, he was out about $150k. The coachwork was really nice, and the layout was unique. It had all the comforts one would need for tailgating with your favorite sports team. But it wasn't all that great for campgrounds.
It only had a sofa, no bed, and so only slept one, though it seated seven. It had a wonderful galley, but no bathroom at all. And when you opened both rear doors, there was a humongous 60-inch widescreen television and kickin' sound system.
When I took him on a tour of my Interstate, and he asked how much it cost, I told him that the MSRP on mine was $135k, but I got it for less. His response? "Dang! If I'd'a known that, I'd have bought one of these instead!" Turns out he didn't even know that RV manufacturers did Sprinter conversions; he thought custom was the only way.
