Keystone's luxury fifth wheel division, Everest, becomes first fifth wheel to document temperatures in holding tank and pass through storage areas during cold weather testing.
In order to prove the effectiveness of the new Therma Shield 37 package and other Zero-Degree Rated components, Keystone engineers consulted with Dometic Group, Elkhart , Ind., to develop and conduct a test of a production model 2008 Everest fifth wheel to determine the capabilities of the Everest during extreme cold weather conditions.
Dometic technicians placed the 38-foot fifth wheel inside their controlled environmental test chamber and set the Everest's thermostat to 74-degrees. The technicians then reduced the ambient temperature inside the test chamber to 0-degrees Fahrenheit over a sustained period of time designed to simulate a typical extreme cold weather camping trip. Test protocol required that temperature thermocouples be placed at multiple locations inside the RV interior and inside critical areas such as the Waterworks utility center, the pass thru storage, and adjacent to the holding tanks. These probes monitored and recorded temperatures as the test chamber was reduced to the target temperature of 0-degrees Fahrenheit.
Results of the test show that the production model 2008 Keystone Everest exceeded all expectations. While the "outside" temperature dropped as low as minus 4-degrees Fahrenheit, temperatures in the living room remained at a comfortable 72-degree average, bedroom temperatures averaged 70-degrees and bathroom temperatures averaged 75-degrees.
All of the holding tanks, dump values and waterlines remained completely operational as recorded temperatures exceeded 45-degrees Fahrenheit in these critical areas thru-out the duration of the test.
In short, conditions inside the Everest test unit remained comfortable throughout the testing cycle and critical components remained operational. These results validate the cold-weather effectiveness of the Everest's Therma Shield 37 package and Zero-Degree Rated components. (Dometic Test No. 0776, Everest Unit #70228)
