Any converting to electric off road examples, perhaps using converting kits?

Hello !

This hackaday blog Electric Jeep With Modified Prius Hardware shows an example of an electrified jeep from this youtube post Boost Charging with the Gen 2 Prius Inverter.

I'd really like to look at examples like this, and now I know the prius inverter is a thing, but I'm also looking for more kind of off road conversion kits, and targeting old but pretty good but sturdy off road champs like different jeep models. And that are not as expensive as buying anew?

The issue with modern vehicles, whether electric or not, is how connected they are, and how they have become like software as a service kind of stuff, so one really doesn't own the vehicle since one needs to keep paying per month, quarter or year, whatever it is, and with all the dangers on privacy and security of generating location and other personal information that can be gathered from the vehicles. There are people that have found ways to hack modern cars to incorporate kill switches and the like, but that's risky if in need to apply for guarantee or similar. Besides, Ford, Bollinger, and Rivian, which are all pretty expensive, there's no much off road options, and maybe converting is the best way moving forward.
