This is a Monaco signature series Castle motorhome. It has four slide outs and is 45 ft long. It has the 12,500 Onan Cummins generator and is equipped with a Detroit 60 series engine that is fairly new as I have a receipt. This motorhome does need some cosmetic improvements however the motor transmission all slide outs and generator work just fine. The reason for selling is I'm wanting to downsize to a airstream. I'm located in Gatlinburg Tennessee.
