Welcome Mainer, this forum has a long history of friendly warm people, originally united by Daniel C. Gene is the historian and I am one of many "redesigners". :E
We just got back from the 'shakedown cruise' to Lancaster, Pa. for the changes I made in our 213. (pix are a few pages back)
First thing is that the word 'shake' applies much less to the coach now. The only bad noise is a creak which I almost eliminated between the frame of the tv cabinet and the angled cabinet on the right. (I forced the frames apart with a stiff putty knife and injected a line of caulk. ) A better fix is in the planning stage!
As for the shakedown, livability has been greatly enhanced. The big aisle is a pleasure and even when the bed extensions are in place. Getting the coach ready for sleep mode is faster than before and much more comfortable. There are a lot less lumps to negotiate. My DW would like a pad of some kind for her side, but the now lengthwise oriented dinette pads are great. There were no new rattles other than the cover of the pass. side box hopping a bit on washboard roads. That was solved by some of those self stick felt bumpers used for cabinet doors.
The new dining table is fine, rocks a bit, but not enough to bother us. It stored nicely in the rear wardrobe, but I had to add a bungee retainer to keep it from rocking. I will be extending the duct cover on the pass side with some kind of legs to hold the bed extensions flat and level. We didn't miss the slightly less storage, and with those neato hinges, accessing both compartments is a breeze. btw, the other 'neato' hinges on the tv cabinet work great and the entire front has a cleaner look.
The new thick carpet was a pleasure to walk on, and provided additional sound insulation.
Last thing was the pleated shower door. Another great improvement. Ease of use and lack of 'curtain attacks' made it very worthwhile.
Of course the big Chevy performed admirably as always. On one section of I-78 there are some kind of "repairs" going on which caused us to porpoise terribly at speed, so I slowed to 50 to get thru it. Otherwise speed was 60-70 on the highways.
The Lancaster area is a nice place to visit. Lots to explore, especially after seeing the touristy places the one required time. Some of the stores we wanted to re-visit were no longer there, but the villages of Intercourse, Blueball, Bird-in-Hand, Brickerville and Manheim are nice and quiet in the off season.
