I will be using my truck primarily for towing/camping duties at track days.

I usually have AC power access at the track and usually just plug my enclosed trailer to one 20 amp circuit.

To be able to charge the truck over a 2-4 day event, I'd likely be limited to a 20amp level 1 charge. That's fine for my purposes, but I also need to be able to power my trailer for lights/mini-fridge/heated blanket/hot water kettle.

Has anyone tested to see if the 120v outlet in the bed of the truck stays active during charging while the truck is off, and if so, how many watts or amps have you been able to pull off it during the charge before it cuts out?

120V stays on. It's a full 15A rated circuit.

I‘d be looking for a second circuit. Either a higher power one like a TT-30 30A circuit, or use a second 20A circuit to power either your charging or your accessories.

I think the manual says that if the 120 V outlet is not turned off while driving it will use unnecessary power. Page 156 of the R1T owners guide.

It uses power any time it's on, regardless of if there is anything plugged in, regardless of if the vehicle itself is on, off, moving, etc. It's probably relatively minimal, but I haven't had an opportunity to measure it.

And the only time I've had it go off without explicitly doing it myself was when the truck performed an OTA.
