It is done all the time in WA. A hitch on the front of the MH is quite common here. The front hitch makes it a piece of cake. Just park the boat in the parking lot, turn the MH around, rehook and launch. With the steer wheels close to the pivot point, you will be amazed as to what you can do with the trailer. We had a very long driveway, the DW would push the boat down it and into the garage, like it was a toy.
