My wife and I will be full timing in just under three years.
We have been doing a lot of research (reading, forums, RV shows, etc...) to try and get as much information as possible.
We attended the Providence, R.I. RV show this last weekend - it was a wonderful show with a mulitude of different units...both fifth wheel and motor homes.  We had a ball looking at all the units.
There was one thing that we noticed at the show while looking at fifth wheels that we hadn't noticed before:
Most of the units seemed to shake about as people entered and left the fifth wheels. 
We actually noticed this, as we were looking at a "top end" King of the Road, Grand Marquis which was really decked out...the show price was around $101,000.00 but  it had just about every option and bell & whistle you can imagine (this unit is also rated for 20 below  zero)
This is the first time we had checked out a King of the Road (and we were very impressed)
In our research, our favorite units have been the Montana (probably has been our favorite for the longest...in a mid-range price), as well as the Cedar Creek, the Titanium, the Teton (which is another fairly high end fifth wheel).
My question is this:
While sitting in the King of the Road (Grand Marquis), we found it to be "rock solid"....we couldn't feel any movement of the unit what-so-ever when the huge number of people were entering and exiting.
However, in most of the other units, as people were entering the fifth wheels, we were bounced around pretty good.
I suppose the issue could have been the manner in which these show models were actually anchored?  Possibly all the leveling jacks may not have been utilized like they would be if actually set up at a campground.
Does anyone have any information or first hand knowlege/experience as to whether one unit may be significantly more stable/more solid or better built, than another......such that one particular unit would feel rock solid where others shook?
Like I said, I do know that these units are obviously not set up as solid/permanent as they would be if they were being lived in.

Is there anyone out there who has first hand experience with King of the Road Fifth Wheels?
They do tend to be a bit more expensive (top end)...with the limited research we have done on them so far, the seem to be a really well built and quality unit.

We do have three years before setting out on our adventure and we are really making an effort to find out absolutely everything before we buy one.  We are gathering brochures, talking to salesmen, using these forums to ask people that already own fifth wheels - know what they are taking about, and keeping a journal of all the info we find.
Hopefully when we buy, we will know "exactly" what we want, and why.

Thanks for any and all info.
