What do you do to protect you and rig at hook-up time?

[RodeWorthy]

Here is an easy one. Tailor made for group participation.

What do you do to protect your rig (and you) when you hook-up at a campsite? This has been covered before but it may be useful to review it again for those of us new to the process.

I have heard of surge protectors for the electric, sanitation of the water spout prior to use, pressure regulators for water supply, pre-filters and water softeners for water supply, anti-bug remedies around the tires and jacks, etc. There are probably many more I am not aware of. Any special tips for the sewer system? Do you pre-test the electric before plugging in?

Please let us know what you do and the products you use to get set up at your campsite.
