Our floor issue was not noticable when we did our inspection. It presented several weeks after we took delivery - likely from expansion/contraction with temperature changes. If it had been visible on the dealer lot, we would have addressed it then... before signing.
BUT... there's an upside:
In just two years our 2020 MH (exact same floorplan) price has inflated 25%... which is ridiculous. The added insult to today's buyers is now only receiving a 15% -18% discount off retail... when just two years ago 30% was very common. Which means our 2020 (with my included upgrades) is selling USED for more than the original MSRP!!
So... whenever I have to "fix" something, I smile to myself and marvel about my "investment" motorhome...
