Taking delivery of a PRO S today. Have a question about how to setup for L2 charging. We currently also have a 5th wheel RV capable of 50amp service. I was thinking of installing one setup outside where I can plug the RV in or plug the EV in. Do I need to put an EVSE in for the EV, or can I just get the right cable to go from 50 amp outlet to the EV? I hope this makes sense ...

if I understand, you will need something to translate the 50A RV plug to the J1772 car plug and to negotiate the amps with the car, which is what the EVSE does. You can go hard mounted or portable based on what suits your needs the best.

Amazon has a ton of them. Amazon.com : portable evse

and Chargepoint, EA, Grizzly, etc...are some of the permanent mount ones

I would. The biggest portable I have seen is 40A, but they only have the RV 14-50 type of plug. I have the Mustart Travelmaster which lets you use different plugs for the most flexibility, but it will max out at 32A on a 50A 14-50 plug. I think some of the hard mounted ones can go to 50A, but someone who has one of those would have to weigh in and that is really too close to the 50A service limit you have. And a 32A or 40A should charge you up overnight without problem. I think 8-10 hours is the time at those power levels or about 24ish miles of range back per hour.

And congratulations on getting the car today! Exciting time!

thanks for the helpful info. I think I'm starting to understand this now. So if I go with something like the Mustart portable charger, I just need to get a 220v/50amp outlet installed outside. The con is that the portables aren't as weatherproof as a permanent installation, and they could be stolen. The benefit is I could take the portable charger with me to the RV park and charge ID.4 there. The alternative is the permanent box installation at my home which negates the two cons, but leaves me w/o portable solution. Is my thinking making sense?

If you decide on a portable, consider enclosing your outlet in an outdoor box that will provide weather protection and can be locked. Something like this? https://www.amazon.com/RVGUARD-Weat...t=&hvlocphy=9013543&hvtargid=pla-895836023656

I've installed this 14-50 receptacle box on two of my friend's houses, and it allows you to shut and lock the cover while the EVSE is plugged in. Could be a good theft deterrent since there'd be no easy way to unplug it.

Great idea!

And here's the Mustart unit semi-permanently installed. No theft protection, mind, but you could set the ID4 to NOT unlock the charge connector when done, in which case car and EVSE are both protected.
Holsters and cable hook are both available from Mustart on Amazon.

I was in a similar situation with a twist. I had a travel Trailer that was 30amp service so I would adapt from the 14-50 plug to my TT 30 Amp. Confirm it, but the NEMA 14-50 should match you fifth wheels 50 amp service. I currently using the enel x JucieBox 40 (Next Gen JuiceBox 40 Amp Car Charger with WiFi | Enel X). It uses the NEMA 14-50 plug as well. It is the plug in version rather than the hardwires version. The mount is bolted to the side of my house and the EVSE is locked (using a key) to the mount. This allows me to share the plug between the TT and EVSE. It is a 40 amp unit and I have charged my ID.4 from 5% to 80% in just under 6 hours ( added 54kWh). I also plan to purchase the Mustart to replace my included Portable EVSE so I have the flexibility to use AC L1 or L2 charging with the different adaptors. Unfortunately I am away from home otherwise I would post a pic.
