A comparable motorhome to a Coach House for 1/2 the cost, yet built real well with great quality will be a
Phoenix Cruiser. If you insist on a Mercedes Sprinter chassis, then you are limited to two Phoenix Cruiser models as follows.
Most popular is the rear corner double bed
Model 2350 seen here offered with a very nice optional slide out.
You can watch the guided video tour
HERE.
The over-all length of the Sprinter chassis version is 24'-6".
The E350 chassis version is 23'-11" due to it's shorter chassis frontal area.
The other Sprinter choice is
Model 2400, also offered with an optional slide out.
Both models are also built on the E-series. We ordered our
Model 2350 Here without a slide out back in 2007. It is built on a 2007 E350-V10 chassis. Like most PC owners, we are still very happy with our decision.
