For internet, I would consider just getting internet off a cell phone plan. Just use your phone as a hotspot. We do that all the time when we travel in our RV. Verizon and AT&T probably have the most coverage. Tmobile and Sprint might have less coverage, but they will be cheaper. If you have an iphone, than it may be ready to go already, depending which company you choose.
For Satellite TV and internet, Dish has month to month contracts, so you can call or visit their website. Direct TV is another provider. But check and make sure your electronics are compatible, as you may have to purchase new equipment ($300-400 for everything). They will probably want you to buy a TV package too. Good luck!!!
I found Good Sam to have cheap RV insurance compared to others. Geico is another company.
