For me the locations that have everything I need are my bases. Most times they even are my only safehouses (I don’t like the command bunkers much, getting out takes so much time).
If I need to have a companion station, I try to get to the airfield in general.
Oh man, now that’s smart! I didn’t even think of that! I’m going to have setup my bases with more stations and use them the same way! Thank you for that idea! 
Man, I’m really glad to be getting this feedback! Thank you to all and if anyone else has something to share, please do!
