Whether or not it's worthwhile depends on you. For me it's worth it. Usually I pay less than what area apartments rent for. Corpus Christi was an exception as rentals there are dirt cheap (and some of the places look like dirt). You need to do your own research for the places you can stay at. www.rvparkreviews
area good place to start. Up north, finding parks that are open in the winter becomes more difficult. I imagine that they have mobile home parks up North. If you are completely self contained and have no need of a bathhouse and are staying for 6 months or longer, that may be a better and cheaper option. You will need to supply your own cable/internet. Possibly put electric in your own name, but maybe not. Depends on how the park works things.
Currently I'm in NM. I have a 30 amp site. $425/mo includes water/sewer/electric/cable/wifi. If my electric use exceeds $60, I make up the difference. It has only gone over once. I suspect the 2000Watt heating element in the water heater is what did it, or they read the meter wrong (or I got a neighbours reading). I do turn the water heater on only when I need it. I plan on getting a DISH antenna in the summer so when I stop again for a long term site, it will most likely be in a mobile home park in FL. Cheaper than RV parks there. And I don't do pools, shuffle board, potlucks or what ever organized activities RV parks have. I have my own washer & dryer so I don't need a laundry nearby. I can and will set up my own hotspot so I don't need park wifi (which is often crappy). I just need a job. I don't travel all the time.
I have found that RV parks that take "workers" tend to have no problem with skoolies. That is what I look for.
