There are some good points in having two motors. When a person never lubes the linkage they get tight. In freezing rain and slush they get stiff. The system is weight and drag sensitive so if there is to much weight or they bind the system stops. Otherwise it would be hard on the motor and who knows what else. Having two motors would help extend and retract in those conditions. In some ways I wish I had two motors. In my 6 years I have had to keep after them. My conditions are horrible at my camp. I clean off 2 inches of mud and clean the hinges when I get there. And yes there is that much mud slop that gets on them even when retracted. You are in a milder less severe environment than I am so you will be fine.
