Not new to camping (we've tented and rented cabins for years) but new to RVing. My wife and I bought a used travel trailer in February and enjoyed so much the three times we used it we went out and bought a new one in October (26 ft RVision Trail Lite). We were able to take the new one out for a four day weekend during the end of October. My Question is: Should I keep the new one covered with a tarp during the winter months?? We live in western Pennsylvania. My concern would be ice and snow build up around the roof vents, antennas and ac unit. Any thoughts??
