What's new for 2018

Nothing concrete, but I have had hints as to what some of the added features for 2018 are

Here's what I think I know

1) windows in sidewalls of some slide-outs
2) black hardware accents (ladder. roof rack)
3) change of material on Ultra-Leather seating surfaces

I would like others who have information  to join the discussion.

1) Side windows on most slide rooms
2) Real leather available instead of ultra-leather
3) JBL custom tuned sound system with Harmon-Karden amp
4) Black finish on ladder and roof rack
5) Liquid springs rear suspension system

And other unspecified improvements.

No idea but I would be curious.

Seems it would take away valuable cargo capacity. But combined with a f_550 now you are taking.
