I watch a lot of RV and Van Life videos on YouTube and a lot of those channels use it and they all love being out in the middle of Vancouver Island off the coast of BC, remote Alaska, etc and having really fast internet for about $130/mo. The only person I've seen have trouble is a couple on a sailboat, it would connect while they were at anchor but not well if they were sailing.
As for Hulu Live, YouTube TV, etc, I would highly suggest easing into whichever one you decide on, like go w/out for awhile and just use a Roku, Fire Tv, free channels, etc to start. My wife and I were addicted to our own cable shows when we "cut the cable", me to sports and action shows, her to Crazy Arse Housewives and anything else on Bravo. We learned very quickly that we didn't need it or miss it.
As for pay services now we've got Amazon Prime Video w/ our Prime acct, and alternate back and forth between Hulu (video not Live) and Netflix every few months, that's it, for less than $20/month. Then for other channels we use an antenna for networks and their free sub channels, then Pluto, Crackle, Tubi, regular YouTube, PBS. Don't just dive in and get a big package of anything, try it w/out any pay channels for awhile. I have added Sling during football season and then cancelled after but I didn't even do that last season, I watch network games and thats's it and that's saying a lot from a guy that formerly hit the couch when Game Day came on in the a.m. and fell asleep on the couch watching West Coast games at midnight. I just don't miss it and don't give a rats arse about it anymore.
