Yes.

That way I have an antenna outside while traveling down the highway.
Again, I played around with the cheap Wilson antenna's, rigging it to the ladder on the back of the RV, using a magnetic mount with a roll up cable. All that B.S. is such a pain. The surface mount linked above works 80% of the time.
Peplink equipment is great for this kind of situation, especially out on the water. The most important thing to look for is the right antenna for your cellular modem to get the range you’ll require. I recommend the Peplink Mobility 42G, (https://www.amazon.com/dp/B097P5ZHSC). It’s one of the best for boats and RVs.

Next, get a cellular modem/router with wide band coverage and dual band support. You might also want to have multiple SIM modem support so that you can get coverage from multiple carriers at the same time. Peplink/Pepwave products are great for this and pair well with the antenna.
