I can only ofrer limited comments. The new Fleetwood has many of the same great service people of the former. Their service is about as good as it gets from them. That counts for a lot for many who caan't or don't desire to do it themselves.
The prices are a little higher than the old. The cabinetry is not as great however. Gota keep it honest. the Eagle etc do have the good wood . The paint is a great this time around as are many mfgs.
The fit and seal of compartments is better. Ths ound system and refrigerator and electric features and so on are just fabulous in the higher end ones. The heat pumps are quieter. The new frames really opened up a lot more storage bay area. The independent front suspension is worlds better than our coach. I think the insulation is better also but don't know.
Things I would like to see is more fresh water, gray water, and black tank capacity. Sure it adds weight but it is great not to limit dry camping because you both take showers etc. Strengthen the frame if necessary. Insulate the tanks and piping so that cold weather is not a concern or requires monitoring. Make the awning full coach length or close anyway and drop down tie downs that detach automatically if the wind or weather causes the awning to be automatically retract. A little electric signal and magnetic latch, maybe.
And paint and clear coats at least as thick as Semis so bugs and rocks especially cause less or no damage on front cap.
