Welcome to the 2023 KW29 club! We picked ours up 12/04/22. My previous Class As were a 1999 Bounder and a 2015 Georgetown. Both had F53 chassis, and the V10. My observations so far...
The new 7.3L V8 is a beast. Ford has replaced the V10 with this, and they're very proud about it. It was designed for their super duty, and commercial fleet vehicles. Lots of low end torque, with improved fuel economy.
This RV is 31', my last a 33'. This one will run circles around the other.
So far, zero complaints about the handling. This came with the MORyde system, similar to what is used in ambulances. It rides smoothly, without driving like a boat (both my Class As), and tracks very well. Very minimal tail wag when being passed by tractor trailers. At this point, I have no plans of modifying the suspension. I did add hardware to my last Class A, and never felt comfortable driving it.
I'm seeing over 8 MPG. My last RV was always under 6 MPG.
I did have a weird noise that I just fixed. I put a video on YouTube if you hear a rattle under the floor, between the front seats.
