Keeping Trailer Safe In-Between Winter Trips

I have a travel trailer that I winterized in November. I am in Virginia so its probably safe to dewinterize in March. However, we have found that we are missing out on some good trips because it is now winterized. I really hate the idea of keeping our unit off-limits during the mild VA winters.

I imagine I can't forgo winterizing for the sake if being able to camp in the winter, can I? Is my only solution to winterize after each trip and dewinterize before each winter trip. Seems like a time and money draw to keep doing that.
