We have a Jayco Eagle 256RKS (rear kitchen)
With any floor plans there are good and bad. The rear kitchen does get bounced around a bit. Our drawers almost always fall out. Everything in the cabinets is all over the place when we arrive at our destination. I've had to re-support the microwave to stop it from falling out and now our stove keeps loosening up.
We do like the rear kitchen with it being right next to the rear door. Our Jayco Eagle does allow full use of the kitchen and fridge while on the road without extending the slide. Next time we are in the market for another TT, we may consider an alternate floor plan
