Jayco Jay Flight Sport SLX 170bh Question

Hello,

I am looking to get a 2026 Jayco Jay Flight Sport SLX 170bh. It is the last '26 model on the lot and they said the '27s will be there sometime within the next 3 months. Does Jayco change or improve much each model year or does it usually stay the same with small changes to looks? Is it worth it to wait?

Thanks
