My FIL has been upgrading everything and showing it all off, which of course makes everyone like him more. That being said, his new truck upgrade (some sort of Chevy Silverado) has been a boon for him when camping. He subscribes to OnStar for something ridiculous like $20 a month for unlimited use and his cell signal is fantastic. He can get a cell signal from the summer cabin when everyone else just turns their phones off. Normally he just opens up the hood and puts a trickle charge on the battery and then keeps his truck in the "not running but still kinda on" mode so that his in-truck wifi stays on. He then parks his truck so the wifi signal goes to the places he wants it to go to. He can easily run a movie off of Amazon Prime on his TV in his new camper and still have enough bandwidth to have my MIL surf on her phone because his movie choices are awful. He is currently trying to figure out a way to not need to open the hood for a trickle charge and instead just have a plug. I have no idea what his speeds are but it seems to do him quite well.
