Thoughts...
1.- There is a post on Yahoo Mirada owners group today about an owner who advises that many of the 2019 components have been upgraded and the seats appear heavier and more useful.
2.- My unit is (so far) the MOST trouble free unit we've owned. This is MH #6 including gas and diesel Winnebago and Tiffin units. The only thing I'm working on changing is the driver seats are too short for long term comfort.
3.- I'll mention that although I like the 35OS model, I DO NOT like longer slideout even with the newer drive system. That was the reason for trading my last one. Those things get out of alignment and you're screwed and stuck where it is if the slide is too far out to drive.
4.- We got ours last year at Motorhome Specialists and it was also THE BEST experience I've ever had on a purchase.

5.- I see you're in OK. We live in Fort Smith, AR and would be glad to give you a tour if desired. It sits in my heated WH and I love to show it off! PM me if I can help.
Thanks - Eric
