You will really want and need a toad. You will not want to unhook the RV and take it every time you need to go shopping or sightseeing or just about anything else. You can get something inexpensive like a used Honda Fit.
I am also a programmer and I work remotely and you will be fine with a very large data plan. However, you will need to carefully check to make sure you will have a good cell signal. There are areas where you have a signal but the speed s very slow, or where there is no signal at all. The other thing that happens is you are at a large park and everyone is using their cell phone for internet and the towers are saturated.
I have found very few RV parks with good wifi. They advertise that they have wifi but then you try to use it and with the slow speed and drop outs, you cannot get anything done.
I do not full time but I spend a decent amount of time on trips in the RV.
