I like to cover mine since I park in a wooded area. It usually is covered with twigs, leaves, etc. which clog the gutters and gives the RV lots of black streaks.
I use an ADCO tyvek cover that's breathable so I don't have trouble with mold. I get 2-3 seasons of use from it.
I agree a drive-in RV port would be easier, but it's not in the budget right now.
