I've already got a 70s Civic shell waiting for some TDI love so I've got that size/use covered
I'm pulling new questions specific for GX470 to this post:
1) How good is the 2uz engine? It appears to be pretty bullet proof with what seems to be typical "replace timing belt at 90k" requirement.
2) How solid is the transmission? I've been jaded against autos since 700r4 hell(four in under 100k)
3) For the year range 05 to 09, are any of them better or worse?
4) Is the nav stuff that bad? I get the impression that hard core GX470 searchers try to avoid it and find the unicorns that didn't have it. I won't be using it as I have a stand alone GPS that I favor especially due to location.
So I have an '06 GX 470 that we've owned since 2010 we've personally put just over 200k on it (bought it with 36k now has 248k). It was my wife's daily for many many years and my tow rig for about six years. They will tow significantly more than 6500 just have to stay higher in the rpms and expect really terrible mileage. The brakes could be better when towing heavier but just go slower and start braking earlier. To answer your specific questions
1. 2UZ is a great engine peppy enough for the truck but really under stressed and there a many examples over 400k with no engine work outside of timing belts which you mentioned. In addition to that we've changed out the radiator twice (popped the side tanks) and the alternator once and timing belt and water pump three times since we've owned it (easier to to both at the same time).
2. Transmission is very solid if you change the fluid. It came from the factory as a sealed lifetime fluid so many have never had their fluid changed. We've changed ours every 60k and never had an issue and I've towed quite heavy with it from Texas to Virginia several times.
3 & 4. the years you specified there really weren't any major changes except 2007 got an aux input for the stereo. Like you mentioned several times finding a non nav unit (which we have and I specifically sought out) is not easy but in my opinion makes it even more bullet proof. You can also find non nav head units for sale pretty regularly in the $350 range. The nav stuff isn't great if you just ignore it completely then it's fine but using anything on that system requires a ton of button pushes and it is very dated.
It sounds like it's a pretty good solution for the problem you are looking to solve. The one thing I would say is you'll never get better than 15.5 MPG in that truck. We've had our's forever and that's just what it gets. I think the best tank I ever saw in that truck was 18 and that was going 60 mph on cruise with just the family onboard. Towing that truck get's single digits most of the time but I usually had 5000+ lbs behind it when I was towing.
They are workhorse trucks although most people don't treat them that way. They are the same base truck as the prado which is the light version of the landcruiser for the rest of the world.
