I never removed TV from any RV left in ares that get down too 30 below in NYS north of Syracuse in the lake effect area.
Never covered any rig I owned. Make sure roof is good and go for it.
I had a Shasta 32 foot from 1987 to 2003 with no leaks and then a 1992 park model till I sold it this ear. No covers No leaks.
But I did proper roof maintenance.
I own a 1990 Southwind that used to sit on the edge of Lake Ontario. Had roof leak but the previous owner did zero maintenance on roof. Fixed leak and no problems.
SO my experience has been that with proper roof maintenance you will be fine sans cover.
Poor maintenance you MAY OR MAY not be better off.
