Streaming Video burns bandwidth.. Unless you have unlimited cellular bandwidth I do not recommend it for RV use.. Period.
Beyond that it is look at what they offer and what they cost.
One "Side note"
American Express Plenti card.. This is a loyality rewards card that works across several different retail outlets, and services.
HULU is one of those services.. BI-LO (Grocery store) is one retailer as is Mobile/Exxon.
Nationwide insurance and AT&T are also on the list, Denny's restaurant and many more www.plenti.com for more info..
Note: I don't sell this, and am too new to the service to say much, There is a "Referal bonus" but I'd have to figure out how it works since I don't use Hulu myself.
