Tesla X Towing Videos

For the electrical engineers that really want to get into the weeds on this, real question for you.
IF you had a Tesla truck and TT and ran out of power in the desert southwest. And you had a trailer with 400 watts of solar, and a 430 Amp/hr battery pack. Along with a 1500 watt inverter.
How long would it take to generate enough power to get the truck, without the trailer, 20 miles, to a real power source for recharging if you dont run anything else in the trailer?
It may be a lot better than I am guessing, but I really do wonder if there is an optimistic answer.
That there is a self sufficient method is a positive, just curious if the method would be real world useful.

You don't really have to get into the weeds or be an engineer to figure this out. Regardless of your available 110V power, Tesla Level 1 charging only provides a max roughly 3 miles of range per hour. TFL testing shows that towing uses roughly 3 times the battery energy as non-towing, so figure 1 hour charging time per hour of range. With a 400W solar panel trying to charge a battery pack powering a 1.5 KW inverter, you're going to be there a LONG time. Even with a gas generator (would probably take a 2kw generator at a bare minimum) figure 20 hours charging time and about 7 gallons of gas. (Honda EU2000i uses about 1/3 gallon per hour at full load) Not very good mpg at all! And if you were using this little generator you would have nothing left over to run anything in your RV. I'd say Tesla has a bit of work to do before they produce a viable vehicle for RV use. But in time it will happen, as sure as the internal combustion engine replaced the horse.
