Thanks SuperD, I have been to the MSHRV website, but didn't see that. I did talk to a Thor factory rep last fall, and he mentioned a few of the new features you mentioned would be coming in the future. I saw they hadn't posted any photos yet of the 2018's on the MHSRV site.
We also liked the fact that the 31L had a large walkway down the center when the slides are in, I can't see them getting rid of that floor plan.
I guess we'll stay tuned
