These have been some really good comments. I have had a 5th wheel and now have a motorhome. We travel for months at a time and then go back home. Passport America
http://passportamerica.com/ is a discount camping site that will cut your camping fees in half. Camping can go from as little as $10 a night to over $100, if you are in a pricey resort. There are many campgrounds that offer a monthly fee that is at least 50% less than their regular nightly fee. Some have specials for staying a week. You will have to call & ask what the fee is at each campground you are planning to visit.
I love the traveling, but, also, love going home. 5th wheels do have a lot of storage. My stash is much too large to even think about moving out of my house. Some people absolutely love being on the road, others hate it after the first little bit. I truly agree that you should rent or borrow or whatever you have to do to test the waters before you commit to a lifelong journey in an RV.
