International Signature Christopher Deam Series. Have owned our trailer for a little over Two years, and have washed, and waxed several times, but have not been able to use only Four times because of family heath care needs. It’s not our last Airstream , and this is our Second. We just need to take care of others first. Bed is perfect, has new mattress cover, and pad. This Airstream is perfect. The first owner bought it to use only at there lake property, and never used any appliances, was only used for there sleeping. Every thing works,and is ready to travel.
