Water heater drain

I winterized my camper. I drained my hot water heater and took the element out. I noticed that there is still some water at the bottom of the heater. The drain sets up a little higher than the bottom and prevents a full drain. I don't think much is in it. Is this normal and is there any chance that the it might freeze up something? Any thoughts on this would be appreciated.

Whatever's there will freeze, but it won't damage anything.

Yep...perfectly normal and nothing to worry about.

Personally, after I flush out the crud using a water wand (photo), I use a paper towel and stick one end in the anode hole and let the other end hang down over the cover.

The water will wick out of the hole and gravity will siphon all the water out.

The problem with frozen water is when it expands and doesn't have room to expand, such as in a pipe or plumbing fixtures like taps. In the bottom of your hot water tank or your holding tanks, it has plenty of room to expand and will not create pressure as it freezes, so it simply freezes and causes no damage, just the same as a puddle would.
