Finally found time to take “Sunnyboy” (our van) into the caravan repair garage, “carafix”, to find the pesky little leak. They found a rivet that holds the awning in place had worked loose leaving a very small hole, but that was all that was needed in torrential rain to get the back corner of the van, over the bed area, very damp.
Half hour later with new rivets and glue pumped into the holes at a very reasonable cost of $40, we are now water proof. We hope!!!!
Now just need a full mechanical check.
22 days to “d-day”………
