OK I hope I can ask some charging questions here? So it looks like Ill definitely have to run a 220 line out to my garage to charge this beast right? Do I put a 220 dryer plug on the wall, or will it have some kind of charging station? What about the cord? Will GM supply us with a 20 footer to plug this thing in? I know no one probably has any idea yet to these questions, Im just thinking ahead.

I would recommend running a 50A 240V line to the garage and use a wallbox from any of the major manufacturers. GM will provide a connector, however we do not know the type, style, or specs yet. Having owned EV's for 8 years, I usually carry the factory connector with me in case of emergencies (have not had one yet). I am currently using a JuiceBox which has worked well, but ChargePoint and others sell a similar product. Is your Electrical service / panel in the garage?
Electric panel is in basement, attached garage but no way this Hummer will fit in it. Ill have to run cord out to it in the driveway.

Agreed, 50A 240V line at a min. If your running a complete new line to a garage I would consider a 100A line to subpanel and then a 50A 220 line. Most of the Level 2 charges available are either plug in or direct wire. I preferred plug in because easy to move on or up if needed but personal decision. I have a JuiceBox and have been happy for the most part but tons of good options these days. Not sure what is going to come standard with the EV but surely in cant be a 110 option like the Bolt and Volts come with. It would take a week to charge full 
. Maybe as an emergency option.

Yeah, I always recommend having an electrician look at your specific electrical service situation before you add any EV charging circuit, different parts of the USA have much different electrical service setups, and so it is really site specific. You cannot cut any corners on your EV charging circuit as it is likely the only circuit in your house that runs at max capacity for hours at a time, and in hot weather during the summer.Agreed, 50A 240V line at a min.

If you are planning to park the Hummer EV outside, I would recommend putting an exterior rated wall box outside close to your charging location. Don't forget to GFCI protect the circuit, previously not required, but is now required by code whether it is inside the garage or outside. Not to be an alarmist, but EV charging systems and circuits need to be respected to keep your home and family safe. I have seen people damage their electrical system, by having improper connections, or a cord working loose in a plug.

We are having a house built, and electric company installed a 60 amp line in the garage with a U065P plug. Will this work for when we finally get an electric Hummer?

UO65P is a disconnect box, that is not required. 60 Amp line is good, you can purchase Charge Point Home Flex wall box and run it at 48 Amps. Remember EV charging is a constant load for hours at a time, so you want to always pull 20% less than the circuit max capacity. It looks like the required plug is NEMA 6-50 or 14-50. Here is the unit, this is the top of the line, and you may get a rebate from your local utility, I just got $500 off on mine. Check with your local utility company. In the area I live we typically use NEMA 14-50, and make sure your contractor GFCI protects the circuit which is required under the 2017 electrical code in the USA. Many contractors are still unaware of this change in the code.

Is this even an option for the EV1? Thoughts?

You mean buying a switch to share a circuit? That is not vehicle specific, that is an accessory
