I’ve had both. I’m a DISH fan now. They are much more RV friendly.
I have a roof dome that I haven’t used in years. I have a Winegard Pathway X2.
ISO many places we stay have trees so the Pathway allows you to put it where it can get a signal. DISH also has a set of sats called the eastern arc and the western arc which are in different aee red as of the sky. You can pick which set based trees etc.
DISH lets you change locals as you move around. Daily if you want. Their app lets you reauthorize you sat box without calling.
No carryout gets HD on Directv. Not a problem with DISH.
