re: Updated Cord Cutting Thread | Compilation of Set-ups posted in post after OP

I apologize in advance for both a long post and my lack of understanding regarding IPTV, VPN etc. I'm also looking to get away from cox, mostly out of spite. I'm ok with their internet until AT&T fiber comes to 70816 (unless you guys recommend something else). I'm searching for a streaming service that I can use at home and in my 5th wheel when I'm away. For my current camper setup I create a hotspot with my cell and link firesticks to it and use an antenna for local. You can already see my problem, no cable channels. I tried out sling this past weekend at the TN game and it sucked. I had no issues with Netflix, prime or any other service but espn continued to freeze with sling. When I ask others with RV's what I should do, 95% say to get a monthly DTV subscription. Apparently there's a service you can use for a month, cancel, use for 2 months, cancel etc. and only pay for the months you want service. I know there has to be a more consolidated way to have reliable streaming at home and away without having multiple subscriptions (i.e. Cox, DTV, Dish) and I'm hoping that someone here can help me. At home my setup is cox preferred (Download speeds up to 250 Mbps*, 1.25 TB (1,280 GB) Monthly Data Plan, and the panoramic setup) at $97/month. Cable is $138/ month, add in the taxes + fees and I'm at $250.
As far as IPTV setup...can I use it in multiple locations (home and away)? Any recommendations on a provider? I'm not saying that cost isn't a factor but if I have to pay a little more to get better service, I'm ok with it. Regardless, I'm sure it will be cheaper than my current cox bill. As mentioned, if there's a better internet plan, I would gladly swap.
Any help is greatly appreciated and I'll gladly return the favor with a few cold ones! TIA!
