Dish pointing

I have a dish in my RV that I set up when we are camping to watch ball games and such.  I take the main receiver from the house and before I left I’d go to Directv’s page that was “dish pointing by zip code” and put in the closest zip to where I’d be camping and use those coordinates.  For 3 years a couple dozen trips I never had a single issue finding the satellite and getting a 90+ signal strength.  That page is no longer available and for my first trips this year I’ve been close to throwing the dish off the mountain!  I have downloaded apps and went to a dozen websites,  each one has menu of 30 or so satellites.  I don’t know which satellites I need,  I try the ones that have directv in the name and no luck with any.
