When we traveled more using the coach, we had one Verizon JetPack and two Verizon Android cell phones for internet and communication. If we used up the JetPack's monthly allowance of 15 GB for internet, then we used the phones' hot spots (30 GB limit per month on each phone) to get through the month.
Now that we do not travel much, we gave up the JetPack and have only the two Verizon Android phones.
For TV we have a single DISH subscription, the Gold 250 channels including the Golf Channel. We recently upgraded to one DISH Hopper 3 and two Joeys. They go with us between our Yuma home, our coach, and our Hermiston home. It takes but a few minutes to move the Hopper 3 and two Joeys from home to coach and from coach to home at both our summer and winter residences. The three DISH devices are used in both houses and the coach.
Our coach had a self-seeking satellite dish, an RF Mogul Eagle III for DISH, installed when we purchased it. It works well while parked but must be stowed while traveling. So... it doesn't work while moving on a highway nor can the satellite dish see through trees, buildings, nearby cliffs, etc.
Unlike most retirees, we manage and trade our retirement funds that are invested in the stock markets. Reliable daily internet and TV reception has always been very important. Thus, we spend more on internet and TV reception technologies than most retirees do.
