I can't speak for all FR products but our 2010 Wildcat 31TS has the heated underbelly. We have it partially blocked off to force more air into the trailer. We don't keep anything in the underbelly except chairs, grills, hoses, etc..

And WATER? ( I only point this out because in the majority of the US this week, if you're not winterized, you better hope you have some HEAT in the underbelly of your RV!)
