Any satelitte systems for both TV and Internet combined?

The answer is perhaps. Or there used to be... But I do not know if it is still.

Back when I had Hughes Net and DIREC TV I had what Motosat calles a "Bird on a wire" this is a DirecTV Single or dual (Forget which) LNB on an arm that hung off the side of the main LNB/BUC arm for the Hughes 7000

Had I had a different Hughesnet assignment I could have hung "Multiple" LNB (triple today) and picked up Dish instead of Directr.

BUT I do not knwo if they are still doing new 7000 installations (hughes) and DirecTV is .... well.. Good chance they will soon drop the satellite that system picked up. and possible go to internet only in the not too distant future.

FInally.... SPeeds on the 7000 were low to mid DSL.. nothing to brag about.

I vaguely recall that Dishnetwork used to have an agreement with Hughes to run it with a 2nd LNB, not sure this is still a fact.

With Viasat you'll want unlimited data plan (kind of, see below). Plans after 3 month introductory catch start from $70 plus tax. This is internet only. Direct TV plans start from $35 for basic plan. Unlimited data means until you exceed 100GB (?) per month. Then your speed drops to crawl. They also have a limited data plan for $50, but it doesn't look good.

Data cap, cost upwards of $100 (for internet+TV) and sub-par speeds make this combo not very attractive.

It "sounds" like DirecTV can be received on Viasat dish, not 100% positive. But it doesn't work the other way around - DirecTV dish won't receive Viasat internet.

Go cold turkey. Camp WiFi where there is any, none where there isn't. Few TV channels of free to air broadcasting where it works, radio where it doesn't.

I believe the Hughesnet satellite internet antenna is still capable of receiving the DirecTV programming with a separate set of LNB's attached to side of the arm used to receive the internet service. It does take a VERY large antenna that you could setup on a tripod and manually move and point at each new location.

and she will be able to fill you in with what's available these days. We are not affiliated in any way but she if very knowledgeable and has been doing this for a long time. Tell her Bill from the former Internet Anywhere said Hi!

I’m in love with Sitara Hewitt the actress spokesperson for the Hughesnet commercial.

I have never talked to a sat internet user who would not trade it for DSL if available.

A carryout auto seek sat for DISH is about $400. Winegard Pathway X2.

Cell phone with a data plan and hotspot capability for internet.

Campground WiFi is notoriously poor.

No,
Dish for TV. There is a couple of sat internet options, but their expensive for really slow service.
Most RVers use cell based internet.

I'd be fine with that. Is there such a product?

Probably not simultaneously, at least not affordably. Receiving TV signals and transmitting outgoing internet packets at the same time with the same antenna is technically challenging, to say the very least, and quite possibly impossible with current technology depending on the frequency bands involved etc.
