Can I leave my T/C plugged in to A/C when not in use?

I leave mine plugged in all the time when it is in my garage. Makes a nice guest cottage. (Actually, DW and I stay in the TC sometimes, when the house is full of guests.) I've been doing this for two years, and all is well. The nice thing is, we can leave clean clothes in the closet and basics in the fridge, and when we are ready to go camping, we just load up fresh food and hit the road.
