One thing for sure that is annoying is the difficulty routing anything from the front of the truck to the rear. Having done both electrical and air lines on mine, I've had to settle mainly to everything on the passenger side. But even getting a 4-pin trailer harness in required drilling through the body in my setup.
But yeah, not to make it a Toyota vs Nissan thing, but there's been nothing on my Pathfinder that's proven too difficult to address in some form or another. Still, I think every make has some bonehead design(s). I still think Volkswagens are the worst. It should be criminal the designs they use.
These are the latest I have from the other week after getting most of the lift done. OME 3" + shocks, IronMan 4x4 front and rear panhard/trackbars, poly bushings. 31"x10.5 Cooper Discoverer AT3. It's my brother's truck that he bought off a buddy for a great price, but since he lives in WA and his buddy lives down in Tucson, I've been the middle man transporting it up here, storing it, repairing it, etc., until we can figure out how to get it up to WA. I still need to swap out the bushings on the radius arms, do the RMS and oil pan gaskets (leaks!), and get the A/C plumbed and charged. I rebuilt the compressor for it months ago, but it basically has to be the last thing done because Toyota sucks. I'll put it this way: if you had to replace the passenger motor mount or the TWO lower radiator hoses, you would have to disconnect the A/C system and pull the compressor because they're in the way. It's crap like that that thoroughly pisses me off, and just about everything on the truck is like that. Front shocks took me 2.5 hrs to replace, rear sway bar about the same JUST to replace the bushings. BS all around.
I honestly think all those LC guys are too chicken-sht to go against the grain and complain about this "iconic" vehicle. I suspect it is durable, but the only way it gains field-serviceability is due to parts simply being available. I'd argue there's quality, but serviceability gets a failing grade. It's been an absolute pain to work on. My mom had an FJ40 when I was born, and my dad always reminds me how much he hated that thing. Everything inaccessible, exhaust manifold kept cracking. I share his disgust from my own woes. At this point, I think the only thing I like are the looks. Once this truck leaves my garage, I'm probably adding Toyota to my banned list, joining Volkswagen.
