Obviously, if you are using the full capability for propulsion, you wouldn't want to draw off the battery.
But say you are a contractor with an F150. You are working 20 miles from your home base, so you need 40miles of range and you can plug it in at the yard for the night. If you have a 200mile range, you have 160miles of range that you could repurpose for other power needs.
Operating a circular saw or a compressor for a nail gun off the battery bank is quite viable and avoids the need for a separate generator. The electric F150s can come from the factory with an AC inverter built in, so you just plug in your tools and start working.
The Tesla option is more of a curiosity as it is only putting out a few amps at 12v. Not enough to run anything substantial but you can keep the RV battery up if boondocking with minimal power consumption. 10amps @ 12v is around 0.12KW. You could pull that for 24hours and only use a little less than 3KWH...out of something like an 80-90KWH battery bank, so unless you are using absolutely all your range to get to the camp site, you can generally get away with topping up the battery.
