My 2012 Sundance 3100ES came with a Dometic 895(X)0(X)(X)400(X) power awning. Replaced the motor under warranty within the first 3 months(virtually no use). Replaced again in 2 years, again with very little use. Question--Is the design defective or cheap/ or am I doing something wrong? Dometic is of little help once out of warranty. Any feedback is appreciated.
