We had an 2006 28ft Sierra Fifth Wheel with a rear kitchen. We had to tie everything down and put locks on the cupboard doors. Everything had to be packed just so. It did not have shocks.
We just bought an older 2001 Citation and it has a rear kitchen. We pulled it 200 miles home and over some rough road as well. I forgot and left the rod for opening the awning leaning against the wall in a corner and when we got home it was still standing there. The chairs were standing at the table un tethered and had not moved. This trailer has shocks. I don't know if that is the difference or just a better build but we were pretty impressed.
