I have never seen the display on an R, but on my 7830 the little display on the right is pathetic.  I would like to be able to have 10 things on the A-post were it is easy to see.   How about front weights that can be removed as a unit with a forklift.  A few hand rails around the top of the cab, so when your climbing tires to wash winds you have a little less stress.   I know the op said tractor engineers, but the mega dealer thing sucks.  When farming gets less profitable, overpriced hard to get deere parts won't sell.  I already say thousands yearly, by using Shoups and Sloans etc.  And I won't drive an hour past a competitive dealer just for green.  At my local mega if your breakdown takes 3 of something, they general have 2 here and 1 at another store an hour away. Make no sense.
