I'm looking at an exceptional 2003 Sandpiper 35' 5th wheel, but it has no underbelly insulation. Can anyone offer any advice on how this unit would be for cold weather use? Not below zero use, but maybe sometimes under 25 degrees. Most use would be summer/early fall, but occasionally late fall. Is it possible to add some underbelly insulation to make it more cold weather friendly. I found only 3 heat vents in the floor, two in living/kitchen area and one in the bedroom. Bathroom has no heat vent which makes me wonder how cold weather capable this camper would be. Any thoughts/advice?
Thanks.
Thanks.
