Not sure, but I'm a scuba diver, and own a few tanks. Here's my take on
it, though:
I'm not so sure I want 3000 lbs of compressed ANYTHING potentially
bouncing around while offroading. 800 lbs "secured" makes me feel more
secure than 3000 lbs "secured".
You need an expensive regulator to bring that 3000 lbs to a usable 0-120
LB range.
But the big kicker is:
I need to present my C-card in order to fill my scuba tanks. No dive
shop as near as my local welding shop. No c-card needed at my local
welding shop.
If I had a Dive Shop closer than the welding shop, the situation might
tip the other way.

Heh. Forgot about that. Absolutely right. A lot more gas is generated by
evaporating C02 than you can get out of a scuba tank.
Go with the C02, or nitrogen.
Just don't lay the tank on its' side while filling your tires.

Re: CO2 Vs. Scuba tank?
I use CO2. I have 10 lb tanks I rotate out. Cheap to fill and safely stored
in my HD rack mounted inside the XJ. I have no real fear of it being inside
as long as it is secure. I love the thing. Once in a while I grab it and use
it to power my Nail gun too.

Re: CO2 Vs. Scuba tank?
There is a notice at the business where I exchange my tanks that says that
no compressed gas should ever be transported inside a vehicle. If your CO2
tank should leak from the valve it could fill the vehicle's interior with
CO2 and displace all the oxygen, which you need. I don't know how likely
this is...
