i took a look at the website.
first, i'd like to say i am very impressed in how thought out this is and how OP fit everything found in larger expedition vehicles in a small SUV.
second, i'd like to say the communication stuff is probably where OP's build is different from other regular builds, to the point that it's probably overkill. i mean, who really needs storage servers and such when portable hard drives and starlink to cloud drives do the job. unfortunately, that department is where a lot of people will not need, aside from the FJ Cruiser itself (i'm sorry, i work on too many FJs and it's hard for me to like them), and that's where people looking for a FJ as their expedition vehicle (again, it's beyond me why someone would take such a small platform for expedition) would shy away from. I know the price tag is in the electrical and the comms and tech stuff, but it's just way too overkill for regular folks. but for folks looking to get an expedition vehicle, they'd be looking at a Fuso 4x4 or something bigger for better living experience. just saying.
third, impressive electrical work, and i say that as the wiring guy at the shop. however, auxbeams... really? those are one of the most popular and yet unreliable electrical components there is. i can't count how many i had to replace because they short out or simply stop working. i understand most money is in comms and other tech components, but running chinesium replica lights and switches made me question the quality of other electrical components and electrical work.
not bashing the build. in fact, i am impressed. i actually learned a few things and am planning to breakdown my truck build on a webpage like that. i can see why OP is asking for the price he's asking, but at the same time, i can also see why people laugh. unfortunately the tech things are just overkill for this kind of build on this platform. if it's a full size, then yes, that totally makes sense. But for regular folks who are looking for a turn-key rig, $125k with auxbeam is just... laughable. let's be honest, not everyone's a YouTuber, and as YouTubers go... they probably much prefer to build their own rigs instead.
