So I have had my Bighorn 3970 for about two moths now and came to find that mice had moved in while in storage. Upon inspection I noticed that the underbelly insulation in the area of the drop fram was not very well installed and I could see straight thru from the storage area to the ground. After eradicating the nucences I went to Home Depot and got 4x8 1/2 inch foam board insulation. I fully reinsulated the full length of the trailer and must say it is amazing how much difference it made in temp. I had no intent on the warmth improvement just keeping out vermin but it is very noticeable the added level of insulation.
