You have a large 5th wheel and will therefore have many problems staying in the Redwoods. Campgrounds in the area were built for 20-25 foot size. Especially state park campgrounds. We have stayed at a fairly new campground just built for the larger rigs. It is located in the Redwoods(only one allowed) and designed for Motorhomes and 32+ trailers. It is called Ancient Redwoods RV Park, and is located on the Avenue-of-the-Giants. GPS: 40.41706, -123.96254. Telephone 707-722-4396. They offer full hookups and 50 amps. No pool or club house or other amenities. They do have restrooms and shower facilities. Office is a curio shop. Address is 28101 Ave of the giants, Redcrest, Exit 667 off Hwy 101. Owners are super friendly and I found it to be safe.
