What are the most common things you use

What are the most and least useful parts you've bought or modifications you've made?
We are going to be using the RV partially as a giant car with a bathroom in it, and partially to do local camping. Currently we won't be taking off cross-country 4 months at a time.
We are pretty well equipped in terms of plumbing and water flow. I did pick up a surge protector and a good quality air compressor, as well as TPMS.

Depending on where you will be camping, check into a portable water softener. If you are anywhere near hard water, you'll appreciate it. I have an On The Go softener that does a pretty good job.
