Glacier National Park charging dilemma?

[CybertruckDV]

We did this exact same trip. I was on MT tires and had probably 280 miles range max.
brought our dog and camped at one of the campgrounds in the glacier national park.
I charged 100% at kalispel charger.
spent a day/night/day in the park.
drove the going-to-sun road all the way basically.
went back to Kalispel charger to continue on our trip to Canada.
We were fine

Did you do the loop? Kalispel to Going to the Sun to St. Mary to Kalispel?

Thanks! Those RV camps are life savers.

youll need a 50a adapter for your mobile charger. mine did not come with one out of the box: https://shop.tesla.com/product/gen-2-nema-adapters?sku=1099344-10-D

make sure you pick 14-50

The 30 amp adapter never hurts. Sometimes the 50's are limited. 2014 was so cool driving from campground to campground across the USA.

I've done a lot of charging at campground electrified RV spots. Check with the site manager. I've always charged at city, county, and state campgrounds. Also I'm an off season camper.

As always, NEC says never charge at more than 80% of the outlet's rated current. At camp sites I use a maximum of 70% or only as high as needed to get it fully charged about the time I want to leave. I often adjust Amps in the morning due to camp mode power use over night.

I'd also have 10-30 and 14-30. I have seen both at campsites that don't have 50A hookups. I also carry 5-15 and 5-20. I've never seen a 6-15 or 6-20 at a campground, but I've heard they exist. I've seen them for outside vending machines, and on parking lot light poles. Check the light pole voltage. It may be 277 VAC. I've also seen the round locking plugs for 240 VAC 30 and 50 amps. Adapters for those would be handy, but limit current to 50% or less through them. You don't have overheat protection. I prefer adapters that have a wire between the plug and socket to lessen strain on the outlet.

I have a 6-50 because my farm had it for welders. I also have one at my dad's home. We used it before we put a proper EVSE in.

At a city run campsite in central WI I know of a super rare locking style 240 VAC 20 Amp plug. My understanding is it predates me, and I was a distraught preschooler when the Apollo 13 launch wasn't live on TV. They have a 120 VAC 15 Amp outlet pair that is split across the 240 VAC. With the right pigtail you can get 240 VAC from it that the Tesla portable EVSE likes. I might have one. Knowing the electrics needed for properly wiring a farm has helped a lot. Yes, I have and can read the NEC code book. Once I get my CT I'll have to visit that town park for the kids in town. They were gaga over my Model Y when I first visited. There now is a ZEF net 50 Amp DCFC at a gas station in the town south of it.

I stick voltage, polarity and ground testers into every campground outlet before I hook up. I likely should get a GFI+surge suppressor. I unplug when it is stormy.

If you make your own adapters, use the highest quality plugs and sockets you can get. I prefer industrial level Hubble. They can get pricey, but I've never had one fail. I've seen many burned up $15 ones. They may work fine for an RV for a few years, but for an EV they die fast. They don't have the build for running at 80% max current for hours on end.

BTW: If your Tesla EVSE halves the current, the plug likely overheated. That likely happened because the socket it was plugged into no longer has high enough clamping force on a prong. The socket needs replacing. Tell the campground.

I have seen some crazy stuff in storms and do the same. I feel vindicated. SO said why do I do that? I say look around. Maybe a hundred metal things in open fields all connected together.

Also that is why we have batteries.

Even if the lightning hits a tree and it somehow doesn't burn a hole into the buried cable, it can induce some damaging voltages and currents into it.

Yes. Kalispel to going to sun road to st. Mary lake. We stopped at the wild goose lookout. And turned around to go back the same way.
it was definitely close. I think we came back to kalispel with teens %s

At a city run campsite in central WI I know of a super rare locking style 240 VAC 20 Amp plug.

The mountain condo we bought a few years back had a baseboard heater wired to a 20-amp 240 volt circuit. Didn't care the for aesthetics of the heater so it went away. Repurposed the 240 v 20 amp (2 live legs) circuit as an EV charger. Charged the CT at 8 to 9 miles per hour even across a 100 foot extension (AWG 10). Thus, overnight was able to add a good bit of range.

Ofc, later the HOA had a snit fit and now bans extension cords. W/o making any provision for EV owners whatsoever.
