We’ve been retired 17 years and RVing all that time, the down side for us is Internet access. We use park Wi-Fi when available but it’s iffy. We have a Verizon JetPack and have it set at 12GB per month and try to come close each month without going over to meet our budget. Sure wish they would offer rollover for what we don’t use. We pay for it, they really should. We like Verizon for the coverage because we move around a lot, but it’s time to look for an alternative.
To answer the OP question, as others have said it’s just too expensive for us to use Verizon to watch movies.
