I am disabled, and i am planning to buy a RV, as its to expensive to live in an apartment anymore. I would like to travel some. i need to know a few things before i buy. I will probably buy a used older one around 8000$ my question are. 1- how reliable are they when there 10-15 y/o ? as i could not afford major repairs. 2- how much generaly does insurance run a yr? 3- how many miles per gallon is the average? 4- when you travel does the local police give you a hard time if you dont stay in an rv park ? example you pull into an supermarket and park for the night or on the street's. 5- what about breakdown service like AAA , what is best for Rv's ? Thanks in advance for the info.
