As with everything, there will always be good and there will always be bad. I was recently asked
why I'm not a fan of Michelin tires, the answer is based on my own personal experience, so take it for what it's worth. Many, many people love their Michelins, I'm not one of them.
Lets face it, if they were all truly junk they wouldn't be left in the marketplace today. My Tiffin remarks are from me personally working on my parents Allegro when they owned it, over and over again. It wasn't delaminated but you sure couldn't close one baggage door at a time. I believe Tiffin called that one a "wet bay" problem, and that was one of the things supposedly fixed during their trip to Red Bay. It wasn't. The funny thing is if you were to ask Mom today she would say it was an awesome trouble free MH. She wasn't the one working on it. Also from friends who owned an Allegro Bus. That had as many miles on it going back to Red Bay as it did in normal use. They have since gone back to a Winnebago.
I will have to say though on Comfort Drive it's kind of like having slides, you don't really need it but after having it you'll never want to be without it again. Take a look at Two Jayhawks post, he didn't think it was a big deal either. Fortunately for us on our test drive day it was a terrible gusty windy day so we were able to compare two otherwise identical units, one with CD, one without. The difference was enough for us to order our new one. When things are good they all drive nice, it's when Mother Nature kicks in that you really come to appreciate CD.
At the end of the day it's your money - spend it on what works best for you. Like I've always said, I don't care if you run a string between 2 trees and hang a tarp over it; as long as you have a good attitude you're welcome around our campfire!
