looking for some opinions here. does anybody use a cargo net to hold their gear on their roof rack? I am talking about stuff like sleeping bags and lighter stuff,not real heavy stuff. what brand works the best? How about duffel bags? I am thinking about buying a few waterproof duffel bags to put the sleeping bags and stuff in. what is a good brand/style to get? sorry if these questions seem silly,this is my 1st time taking the xj camping with the kids,and need all the storage area i can get. thanks for the ideas,Ben
