I have a 2013 Cedar Creek fiver that has the automatic bells and whistles. It even has a remote control so I can lower the automatic levelers (I love the 6 point level up system), open the slides, put out the awning and even turn on the porch light. The only thing I have to do manually that is different from a MH is disconnect the truck. With that said my father has an MH and I can get set up just as fast or faster than he does, especially when he has to disconnect his toad. But I have to admit it is nice to be going down the road, as a passanger, in his MH and be able to use the bathroom, grab a bite to eat and stretch out.
But as everyone said, you have to do what is best for you. It is a tough decision.
