Regarding this question -

I asked my accountant today and this is the answer he provided:
"NO YOU CAN USE A PO BOX  WE DO IT ALL THE TIME  SOME AREAS DO NOT HAVE HOME
DELIVERY AND ONLY USE PO BOXES"

This is not correct.

First of all, it's not a "PO box" -- those are only found in Post
Offices.  It is what the post office calls a "private mail box" or PMB.

Secondly, the IRS doesn't care one whit if you file your taxes from a
PMB.  We've been doing for many years, as have tens of thousands of
"full time" RVers.  All they care about is that you pay your taxes, from
someplace.

That being said, many states do care.  Our declared domicile state of
Washington, for example, while it has no income tax system, wants a real
address for voter registration and vehicle registration.  We have such
an "address", but since it has no structure on it whatsoever (it's an
empty parcel of land), the US post office will not deliver mail there.
No problem -- voter and vehicle registration agencies allow us to use
our PMB (which, ironically, is in a different county), so long as we
have at least informed them of the legal address.

The state of Texas, another no-income-tax state, does not have this
problem, and there is tons of case law supporting it.  Thousands of full
time RVers legally "live", vote, and register their vehicles from a PMB
service in the tiny burg of Livingston, home of the Escapees RV club.

Each state has its own laws regarding what is required for voter
registration, payment of state taxes, and registration of vehicles.
However, there is now a nationwide lobbying effort being undertaken by
several RV organizations, including the manufacturing lobby, to ensure
that full-time RVers with no fixed address will be legally entitled to
vote.  (See here, for example:
http://fmca.com/motorhomerights/updates/2007/1107_tn_voting.asp)  At
this writing, voters in many states, ours (Washington) included, are
required to have a fixed address other than a PMB or PO box in order to
vote, and the RV lobby is trying to get this fixed.  Perhaps the
cruising community might wish to join forces with this effort.

FWIW.

No, but you can go to jail.  It is a federal offense to use "Apartment",
"Suite", "Unit," or any other moniker on a private mail box address.  It
did not use to be so, but legislation was passed and the USPS began
cracking down on this a decade or so ago, at a time when there was a lot
of consumer fraud involving "businesses" with "Suite" addresses that
were really just mail drops.

The postal regulations now permit only two ways to address US mail to a
private box: "PMB" (which was the only legal means written into the
original law) or the number sign (#), which was re-permitted after
floods of protest about the original PMB legislation.

Private mail drop services are required to register as such with the
USPS, and, as part of the registration process, they must agree to
inform all their customers of these addressing requirements.  They can
get in big trouble for continuing to deliver mail addressed to
"Apartment" or "Suite".  That being said, both the service and the USPS
do understand that sometimes it is darned near impossible to get mailers
to understand the distinction.

I have even found US government agencies that, when I submit my address
as "xxxxx Rd., #123" mysteriously turn that into "Apartment 123".  It is
the discretion of the local postmaster whether such an item will be
delivered to the mail receiving service or returned to sender as
undeliverable as addressed.

In our case "Suite 209, #324" the 'Suite 209' represents the UPS mailing
service physical
address in the shopping center, and '#324' represents our PMB in Suite 209.
So I guess we are
legal since we use a number sign (#) for the box.
