leaving dog in RV

Our lab will do fine in a train, plane, automobile, or the RV. She just wants to go! Our little one was hesitant until she realized that DW had brought along her bed with the bones hidden in it. Now if you put the steps down she will go inside and look for her bed, if it's there were good to go, if not she will go back inside and wait for DW to load it in the RV.
As for the barking, the campground or your neighbors will let you know if it is a problem. We have yet to have this problem but then neither of our dogs are barkers. A fan, tv, or radio doesn't hurt.
