Having had both, I prefer uncovered. We don’t camp in cold weather, so heat and insulation don’t matter.
Our previous 2007 RVision TrailCruiser C21RBH had a sandwich floor & enclosed underbelly, our previous 2008 K-Z Spree 240BH-LX had a solid wood floor & enclosed underbelly, our current 2014 Coachmen Freedom Express 192RBS has a solid wood floor & open underbelly and I've not noticed any significant difference in comfort level inside any of these camper when the temps are between freezing and ~ 100F. What I don't care for is having to open up an enclosed underbelly for any repairs or modifications I may want to make - a real PITA compared to an open underbelly where the entire underside of the trailer is readily accessible.
