Just returned from Huntington Beach State Park, SC after a week camping. The only time I get to wash the rig is while camping, so I use Craftgate USA Wash N Wax. Just put three cap fulls in a small bucket of water (about 1 gallon), and two microfiber towels. One towel goes into the bucket, use it wipe away the mud, dirt, etc, and the other to buff the haze. I did the 5th wheel over 5 days (not working hard here on vacation), and the truck in one sitting. Can be used on all surfaces, (glass, fiber glass, plastic, etc). Here is a picture of my truck, it poured down rain right after we drop the 5th wheel at storage. The truck is a 2001, and gets washed once to twice a year.
