RV parks/camp grounds

RV Parks, resorts, camps etc. vary a lot in looks, amenities, scenic beauty, etc. There is some consistency in KOA franchised RV parks. They offer call-ahead reservations and discount plans and have generally clean restrooms and shower facilities, convenience stores and campsite hookups. AAA provides "trip tiks" showing your planned route and RV camps along the way. If playing by ear, find an RV park by 3-4PM and get settled for the night. Prices per night vary but an average of $45 with full hookups is probably common. US and state forest camps are popular and many require reservations 6 months in advance. Local events and national holidays often mean that forest camps are full-up. Some Walmart stores allow parking overnight, without charge, depending on local regulations. RV resorts are usually fancy intended for large Class A motorhomes and are expensive for well healed RV'ers. You'll probably get a ton of advice
as this is a big complex subject. Don't get caught trying to find an RV park after dark and seeing nothing but no vacancy signs. Don't park in rest stops to sleep, there is danger of being harassed or worse by local yokels.
