Known Problems

Unlike most Sprinter conversions these models had the back doors removed and replaced with a fiberglass and metal wall. This made easy access to the tail lights more difficult. For example, on the model MB220 with the dry bathroom vanity you need to open the cabinet to get to the panel to remove and replace bulbs for the passenger side tail lights, while on the drivers side you need to remove a panel in the shower. Not an easy feat.


The 2004 Model MB220 with the dry bathroom had the generator exposed behind the drivers side door, cut into the side for easy access. Later models moved it to the passenger side where it was accessible behind another door, located in the space below the wardrobe in the dry bathroom. This easy access to the generator was advertised as differing from their competitors with the line, "How would you like to check the oil in an underbelly generator in the rain and the mud?"

The spare tire on the MB Cruiser is in a fiberglass hutch extension on the back of the vehicle, locked with a STRANGE key you don't want to loose. Also in there is the dump hose, power cord, and lots of space for other sundries you don't want floating loose in the cabin.

The gravity water fill location is above the driver's rear tire and it fills a tank located under the couch between the hot water heater and the furnace. Most of the water lines were visible in this area. With the water lines located in the heated interior this is likely a good design for use in freezing conditions. The grey and black water tanks were mounted to the rear and underneath the vehicle, where the spare is found in standard Sprinters, so anti-freeze for these tanks would be necessary in freezing conditions. Draining the lines for winterization is also accomplished right under the couch by opening valves for each tank that dumps overboard thru the floor.

The sofa can be converted to a bed simply by grabbing the backrest and the two bars that hold it in place to allow it to swing in front of the sofa and continue out to a bed. The bed will now touch the dinette as seen in the above floor plan, and it places your head right at the outlet of the furnace.

The coach battery is located under the back dinette seat, while the breaker box for the 110v is under the front. Did not see an inverter but most places there were both a 110v outlet and a 12v outlet in the form of a cigarette lighter plug. Maybe there wasn't enough space in there for another battery and a powerful inverter. Most Sprinters keep the inverter under a seat in the cab, the under seat spaces are for storage on the MB Cruiser.

The roof TV antenna is the Winegard RoadStar antenna and does NOT need to be cranked into position, so you can watch TV while driving (Good luck with that).

On this edition the fan in the bathroom was not thermostatic nor did it have a rain sensor. Easy upgrade.
