Jacks down during winter storage?

Let's add x3 on my part. I know that there are a lot of RVers that use their auto levers through the storage months. I prefer that my unit be close to level while in storage even if it's just for a short period of time and as mentioned above, I don't like having the finished metal exposed to the elements. My "free" parking spot here at the HOA is not level from side to side so I use the old style orange interlocking plastic leveling blocks on the low side. Does a reasonable job as the spot is very level from back to front.
