My husband and I always spent a month each year camping at Florida's beautiful parks. We each had a plastic laundry tub, into which we packed our clothes and shoes for the trip. That's all we took. Jeans can be worn several times before laundering. We packed for different weather, too, so we took layers. Once camp was set up, we stowed our winter gear in the vehicle.
It's camping, for heaven's sake. When we used to camp with a bedroll on the ground, we didn't change clothes at all, all weekend. It added to the whole feeling of roughing it!
