What percent of the time do you leave your TC on your truck?

I leave my camper on about 75% of the time. I am a last-minute weekend warrior so having it already loaded makes it easy to leave on short notice. Also being in California it will be my fire escape vehicle if I ever need it.

It might just be paranoia, but its an older 1989 Lance camper and I am trying to limit the chances of a wood frame failure from loading. She definitely creeks each time I jack her up.
