The Jaycos ride a little rougher...because they're basically built on a modified 5-ton straight-truck chassis. I rather liked the Polazzo, loved the layouts and thoughtful touches.
It's a tough call, because both are well built units. Jayco's build quality is top notch, and Thor's Polazzo has really come a long way. So I vote you pick the one that has the best floorplan. Maybe take both for a spin too??
