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

Up until this year TC was loaded just during summer months ready to go. When the rains start in OR (approx Oct) - TC use to go in a barn. Barn entrance would not tall enough....so we built a trailer for the TC. I lost access to that barn this spring...so TC lives on Truck under a cover in a storage yard for now. I prefer to store the TC undercover when possible.

BTW - I love drive our DRW F350, however, when in most parking lots in Eugene - I need to put a tire on each parking lot strip to park. - classic liberal town!
