Alice, trying to decide on buying can RV is a hard choice. One thing for sure doing the RV thing is not cheap. Buying an RV has worse deprecation than cars. It is not an investment like buying stick built house. There will always be something that breaks that needs to be repaired. Then there is all kinds of upgrades, better batteries, better steps, better tv antenna, better tires, better brakes and the list goes on. I store my RV (5th wheel) at a very nice secure RV storage facility I use to pay $40 per month for a back-in and now pay $60 per month for a pull thru. Insurance coverage for RV's are all over the place. Some insurance company's may cover your cars & home but not an RV. Some RV coverage could be as little as $150 a year or could be triple that depending on where you go. As far as RV parks most are around $40 per night but some could be $100 a night in California. The bright side of RVing is you can go where ever you want stay as long or short as you want. You get to meet a lot of nice people out there on the trail. Good Luck
