Drained and winterized...no heater necessary. RVs sit on dealers lots thru winter
Slideout working OK...then it may have had some ice
How long did you have it out showing off to friends....from your post thought you had run it out showed rig to friend and then had problem retracting slide.
ALWAYS clear roof of any snow/ice/leaves/twigs etc. BEFORE retracting slides
Your old rig must have had a tear/bad caulking/poor seam etc. for roof of slide to have been water damaged
We have had 2' of snow on roof for a week...2" of ice build up for days....bucket pouring rain events and no problems with roof.
Enjoy your new rig and save the paranoid for UFO reports
Is it time for your medication or mine?
