The only experience I've had with "covers" for vehicles or RVs is on a vintage 65 Mustang. High dollar "cover". Supposed to protect and keep it from harm. Removal of the cover after the first winter/spring revealed that every corner of the pristine paint job was scuffed by the cover
. Cover in the trash.
For the RV we have the perfect solution; 18x60 enclosed, insulated steel building.....much nicer than scuffed paint
