Keep in mind there are two types of cellular boosters, one for mobile use and one for stationary use. For my tow vehicle, I use a weBoost (was Wilson Electronics) Drive 4GM. It lights up the cab of my F250 and allows everyone in the truck the benefits of extending the range of the cellular towers by about 25 miles. When we set up camp, I have a weBoost Home 4G system that we use. It has a more powerful exterior antenna and amplifier and will light up a 500 sq ft area, so perfect for an RV. The best thing is that weBoost products will work with any carrier. Before I installed these, I often found myself disconnecting from the trailer and driving into town to try and get a signal. So long as I have a little bit of signal (you know the one where you have a signal but when you call it ends up dropping) I can now amplify it and get the best signal available.
