You can add "portability" to your residential plan which will add $30 a month to your bill, or you can go for the RV plan for $135 a month, which you can "pause" the months you don't use. I am not sure about "portability" but with the RV plan you have a lower priority for bandwidth than the residential plans. Still decent speed and low latency from my experience, but I am sure that it would be worse if you were in a congested area.
Been lurking here for years and never felt the need to create an account, until recently I had to ask someone a question. :-)
