2010 Keystone Hornet 31RBDS for sale. We bought this trailer with the intention of using it often. Instead it has been rarely used. Has been very well cared for. The trailer has never been smoked or had pets in it. The trailer still smells new. When we bought the trailer we traded out the queen mattress with regular mattress, there fore the trailers queen mattress has been kept in a plastic cover and has been in storage. The mattress has never been slept on. Also the 4 twin bunk bed mattresses have had a plastic waterproof covers on them since the date of purchase. The trailer can sleep 10 comfortably and has plenty of storage.
