I drove from Dallas to Durango, CO (800+ miles) in my previous Roadster 2.5 utilizing RV parks and the Universal Mobile Connector. I was able to do it in 38 hours. I planned ahead using the internet (plus the help of some kind friends) and ensured that each RV park had a 50A hookup. This allowed me to charge at a consistent 40A using the UMC and usually only took 3-5 hours each stop. It's not always perfect, however. Some of the stalls they'll put you at have electrical issues, so you'll need to keep an eye on the car and make sure it's charging consistently. I checked on mine every 30-60 minutes after losing two hours of time at a stop that I didn't check on the car (it had stopped charging one hour into its session).
The key is to plan stops in the threshold of 120-180 miles of each other. I didn't go further than this on one charge, due to the extra time it takes to charge from lower states-of-charge and also the stress it puts on your battery to frequently drive in the below 10% and above 90% ranges. In planning those smaller strides, you cut down charging time as well as strain on your pack. The furthest leg I did was 188 miles, and that's the only one that I did a full Range Charge for. I typically charged to full on Standard Mode but switched the car into Range Mode when driving, which unlocks the bottom 25 miles or so of the pack. In your car with your amazing CAC value (yes, I found out), charging to Standard and switching to Range while driving should give you over 205 miles each time.
I called ahead to each RV park and made sure it would be okay. Most of them only charged me $5 to $10 for use of electricity, but one of them wasn't so kind to the idea and charged me the full $38 nightly rate for "loss of business".
The best thing to pack for this trip? Patience. Me? I'm probably a little more insane about these cars than most, so I enjoyed every moment. You might too! Most RV parks have nice lobbies with A/C and snacks, drinks, etc., so it isn't that hard to relax or explore the area while the car charges. I stupidly did my trip in the middle of July, so the temperatures were very rough in Albuquerque and west Texas. This time of year is likely perfect for you.
Ideally, if you had a Can Sr., you could plan the same type of trip using Destination Chargers - or, a combination of both those and RV parks. If you don't mind taking your time and spending more money, Airbnb's are awesome as
@hcsharp noted.
It would also be important to perform an annual service beforehand, just to ensure the car's PEM is in the best shape.
Hope this helps! I'm traveling and on my phone, so I can't include the old thread to my adventures (which I didn't even finish because I'm a horrible person), but perhaps my friend
@Roadster could include that link for me?
