Would 2M only suffice for the "email/packet" end of
things tho? I mean.... since an RV will be moving
from one area to another.... does that affect the
transmission and reception "protocols" of email sent
via 2M packet?

The availability and density of ham packet-radio nodes (whether on 2
meter, 220, or 440) isn't what it was a decade ago. The widespread
availability of Internet access, and the low costs and high
bandwidths, have lead to a big "decay" in the amateur radio network.
Even here in the SF Bay area (densely populated, high-tech-oriented
population) there just aren't more than a handful of 2-meter and 440
packet nodes and BBSen left operating, and most of them seem to be
special-purpose rather than being set up for open use.

In order to use packet at all, you have to find a node or BBS in your
area, and that's not necessarily going to be easy. You'd then have to
find out what sorts of connectivity and services the system provides,
figure out which of several semi-incompatible networking protocols it
uses, come to an agreement with its owner/operator to make use of it,
etc.

HF packet (e.g. PACTOR, or AX.25 using a slower bit rate) helps to
some extent, as it can be used over long distances where there are no
local 2-meter/440 nodes. However, it's even slower and is subject to
HF propagation issues.

Understand. But since things are automated and once I
buy the equip I have it and there are no other monthly
"costs"..... what will it hurt if it takes all night
for the rig/computer to send that email message? Cant
it be doing it's "thing" (sending and receiving email)
while Im asleep or doing other things?

Maybe so, maybe no.

Remember, the FCC rules generally require that you (the amateur) be in
control of your station. Even if you use automatic control, you're
responsible for making sure that you do not interfere with other
amateurs' communications.

Also remember that there are legal rules concerning what sorts of
transmissions you can do... nothing "for profit" may be of concern.
