I had Directv for years.
Switched to DISH a few years ago. MUCH better for RV use and I thought better customer service but I haven’t had any equipment issues.
I use a Winegard Pathway X2 auto align carryout dome with a 211Z.
Plug it in, click the built in menu that recognizes the dome.
You’re done. $400.
DISH has Eastern and western arcs so better chance for signal with trees.
DISH App lets you reauthorize your box without calling in.
DISH to GO lets you download tons of content to iPad or device to take with.
DISH is a little cheaper.
No carryout gives you HD with Directv.
