Issue with 'mail forwarding address' can be with banking institute and investment institutes
Some will NOT accept/recognize the PMB address as a real physical address.
That and the fact that you do NOT really have a 'physical property address' they get nervous that you will abscond with their 'asset'
Investment institutes may not recognize the PMB address as an acceptable address
These are both issue that some FTrs have had and posted on RV Forums about.
Just information to be aware of
We used a SD PMB and had no issues.....
We also had Verizon cell/internet
Internet was via an air card
We also had a 'truckers antenna' that we would hoist up the ladder IF we had weak signal
As long as we got the 'tower' indication we would use the antenna and plug into cell phone OR air card and get good service
Most of the time during our 7 yrs FT traveling we had good signal
Now there are better means/methods available
You should be able to get good internet service and NOT all that expensive.
