We have been in our 3580 6 days now and love it, got a question for you all. We had snow and wind a few days back and I noticed around the slideouts got alot of cold air coming in along the sides of the slideouts. I put some roll foam insulation in as a temperary fix and it sure did help. Its like the slideout is not coming all the way out to seal the air out. I never had this issue with my last 5th wheel. Does anyone have a suggestion ?? please tell me this is not normal for Big Horn. What is the permanent fix ?? Is it something the dealer can do ?? There is almost a 2 inch gap from the slideout to the wall. I ordered this unit with dual pane windows to avoid air infiltration issue, now I got the same problem only in the slideouts.
