I think it is much bigger than just Q. We were in Palm Springs at the TT campground for 2 weeks. Normally anytime from T-day through late march there are only a few empty spots anywhere in the campground. This year huge holes through out, we didn't have anyone closer than 2 spots away in any direction for 5 days and then only got somebody behind us for the last few days.
Rangers said they had never seen it before either and some had been there 5 or more seasons. Nobody is sure why, figure gas prices may not be cheap but better than some of the prices we have seen the last 1/2 dozen years.
See the RV dealers still selling coaches every week of every description, new to used, big to little and every class and model of trailer. :?
