I bought this2020 Coachmen clipper cadet in 2021 used, unfortunately for me the extended warranty does not cover the sub floor in the shower stall. When you step in the shower and stay to the front of the shower it's fine, if you step to the rear, it spongy. The manufacturer did a substandard job when they installed the shower floor and left it up to the consumers to repair an issue that should have been handled by them. I already contacted the company, the person I spoke to want a picture of the floor. That's ironic considering you don't see the mistake you have to step into the shower to feel the difference in the floor. Just be careful when buying a used RV. Show less
