How do campgrounds charge you?

Just search some campgrounds and check out their rates. Many places have daily, weekly and monthly rates. Monthly rate may have separate electric that's metered (IE separate bill). FHU - full hookups: water, electric (30 or 50 amp)and sewer cost the most. You may also pay a premium for a pull-thru. Just depends upon what you want. Many people like state and federal campgrounds for price and more of the outdoor experience. These tend to be more primitive (fill water on way in and dump sewer on way out with electric on site). Some like more of the "resort" experience and want the FHU's, pools, playgrounds, etc... I've looked at sites on the water front for over $100 per night. Whatever your price range there is probably a CG to meet your need. At 36' long and 13' tall I do not fit in the local state CG. Some CG's do have an overall length limit. Some older State/Federal parks have a 25' length limit and some "modern CG's" have a 40' limit.
