The 2010 model was produced well before the covid RV construction boom. Four season construction provides warms in the winter and lots of insulation for the summer months.

The RV is kept under a cover (pictured) and connected to 30AMP power when stored. A portable dehumidifier keeps the interior moisture and odor free during storage.

We just returned from a 1500-mile trip to Tennessee and would confidently head out cross country tomorrow. This is a reliable and well-maintained trailer that is ready for many more years of travel.
