The mobile charger would be good for most people if they have a proper 240VAC outlet I'd think.
My EVSE was a hardware option but really simple to install 2 feet from panel.
BMW i3 and Chevy Bolt.
I spoke with quite a few highly trained i3 techs (even German) and all of them said no reserve trying to fix an issue.
Every Bolt technical manual says no also.
I'd like to order a Pro but I don't think common users can order them. Doubt Ford will want to make many either. Hummer VP just had an interview where they mentioned that they wanted to put all the options on the first model.
My two EV's don't have any hidden reserve. You can charge to 100%. The issue if going to 0 is kind of sketchy. Various things start to happen once you get close to some low point. Things stop working, things make warnings and the car will usually slow to a crawl and report all sorts of things...
My first EV was a BMW i3 with range extender. On paper I should have been able to make the 65 mile trip each day on battery and usually did but just barely. I spend most of the winters driving a loaner car because the REX was always throwing a code. Then you had to change oil and filter and put...
Unless there are reliable and inexpensive public charging at places where someone normally goes or workplace charging then I don't believe anyone will like charging away from home. I find that it is a small hassle to plug and unplug each night at home. I can warm or cool it on home power before...
We currently don't know what motors are being selected for the F-150. There are some newer motors that are quite efficient but I don't think it'll significantly do better than a Rivian. I'd look to the technology in the Mach E and use it for consideration
Before I got too far ahead of myself I think I'd discover if in fact you do need the full 80 amps. It may be possible that this charger has a jumper to select different current levels.
There's a little bit more to selecting the proper wire size. The type of cable selected the size of the conduit...

I think on an F-150 at 70 flat road moderate temperature you'd be lucky to get two miles per kilowatt average.
