We had very little snail mail.......bills were via on-line banking/E-billing.
Did as much as possible via on-line.
So when we got some where and knew we would be there for at least a week we would then request mail forwarded. Used USPS Priority and got it usually within 2 days---3 at the most.
If the CG didn't accept visitor mail we would find local PO that accepted 'General Delivery' and have it sent there.
Do to very little snail mail we wouldn't request mail for several months.
Having very little snail mail mades it sooooooooo much easier to just follow the front end of truck and go where/when we wanted
