Lucky You! I have had 2 similar experiences on two enclosed trailers, not RVs. Both times after returning from long trip, parked in driveway, one went flat immediately, steel cords sticking out the sidewall, and the other a nail in tread, flat in the morning. My only on the road issue, yup a blowout, about 2AM on New Years Eve, temp minus 10 F, high wind, blowing snow, no shoulder on road. That was a single axle, open sled trailer...don't want to talk about that one.
