YOu may wish to consider DISH instead of DirecTV Since AT&T took over DirecTV they do offer Sat-TV/Internet bundles but.. they are different services. either two dishes (Via-Sat is the other dish and not really a good RV choice from what I understand) or Internet yia land line (not good for RV either).
Xfinity (i think) if you have an account (VERIFY BEFORE YOU BUY) you may be able to connect as "Guest" on other people's routers VERIFY BEFORE YOU BUY. I AM NOT SURE OF THIS.
DirecTV I'm told is dropping or has dropped service on Sat 101 (SDTV) but is still prociding 99/103 (HDTV but rumors abound on the future of it as well as AT&T tries to force everyone to land line.
Dish still works.
Direc HDTV only works with Dish style antennas. Domes and In-motion are not going to work Dish it's a bit more complex
A Single channel receiver will work with a Dome In-Motion or not or with a Dish provided the dome is one that can re-point under receiver control This includes most of the portable "Cube" or Dome type antennas.
MUlti-channel systems need a Triple LNB dish or multiple domes as sure as I'm typing one channel is going to be looking for one satellite (bird) and the other(s) will want different bird(s).
NO matter what antenna you use get one that sets on the ground away from your RV (Even if you have an automatic on the roof) as.. Well the evil signal eating tree I am parked under as I type will eat the roof mount's signal.
Finally: Do you really want to pay 100/month give or take for TV when .. Well I( pay 25/year for a TV guide and use my "Batwing".
