DISH user. I use a Winegard Pathway X2 auto align carryout dome. $400.
It enables you to select the eastern or western arc sats which are in different areas of the sky which gives you options when fighting trees, mountains,etc.
It does not support the Hopper Joey combo. I use a 211Z sat box. You can add a USB hard drive for basic DVR function.
DISH is much more RV friendly than DTV.
You can reauthorize your sat box from your phone for instance. You can change locals daily if you need to.
I have a roof dome but haven’t used it in years.
