Hi everyone! I'm new to this winterizing thing with my 2006 RKS...I'm going to skirt it with 1 1/2 inch celotex foam board, but was wondering if I need to have a heater, like an oil heater underneath as well? According to Keystone, the R value of my unit in the floor is 27. Learning as I go.....just want to avoid unnecessary surprises this winter!
