There's a little math you can do to figure out what you'd need. First how big are the batteries and how long do you want it to take to charge back to full?
Let's say for argument's sake that you want to charge to full in less than a day and you will sometimes want to drive during daylight hours. Your truck's battery is 115KWh. That's a lot.
I don't know where you live but let's say you get the equivalent of 5 hours of 100% sun. You'd need 23000W of solar panels to charge up every day. If you're willing to put some work in you can get the panels you need for about $0.20 per watt, or $4600.
Ok, that's a huge system and you probably aren't driving the range of the vehicle every day. Let's consider a system that's 1/4 of that. This means you can continuously drive 1/4 of the range and charge back up, or charge to full over 4 days.
Then you're looking at a 6000W system and things get a bit more reasonable. You need about $1200 in solar panels. Then you need an inverter that handles 6000W easily, Maybe $3500. Mounting and wiring will cost some more, but you can do a lot of it yourself.
This assumes you're allowed to build an off-grid system. If local rules prevent that (meaning you have to feed back into the grid), costs go way up.
If you want to charge your vehicle at night, and use your fancy system to run a toaster or something, batteries aren't so bad. A lot of DIYers are taking batteries which have finished their useful life inside a car (Nissan Leaf batteries are popular) and giving them a new life (at reduced capacity but you plan for that) in a home solar setup. If you want around 20KWh of storage it might run you $3000. Then you get a charger (another $1200) and the system works like this: panels feed the chargers, chargers feed the batteries, batteries feed the inverter and the inverter feeds your truck. That way when you aren't using the sun it's being stored so you can pull from it at night.
I'm sure I've got some details wrong, but I'd love to hear from people who have tried this at their homesteads. I'm aiming to build a 6000W off-grid solar setup with 20KWh of batteries for around $10k, and go with electric machines over gas whenever I can. I know it's going to be a challenge, and impractical in a lot of ways, but that's the fun part.
Good luck with your setup! The E-F-150 looks awesome!
