I'm in the use what you have camp too.
If you have to buy just 1 in the USA, and 80 can do basically everything here.
More modern Land Cruisers have more power and comfort.
But if you're building an offroader, the newer and more expensive Cruisers are too nice to take anywhere that threatens the body work.
And, a Domestic Pick up would make a good base for an adventure truck, minus some of the more technical trails. But you'd get power, availability of spares/repairs, and honestly, newer ones have good build quality (at least Ford and GM). Diesel versions easily available.
Agree with this ^
For me decisions for truck went along with changing needs and compromises that came with need for more space. When it was just me my 40 was all I needed. Then with two of us and dog we went to a BJ60. Then with four plus a dog the 60 even with trailer was pushing the 3B diesel too far. Now its domestic crew cab diesel as the primary family camping and road trip unit . Mind you, this is for camping and short trips for up to 3 wks, not true 'expo' use. Probably wouldn't trust the pickup for a multi continent trip or anything. I'd take the 60 for that instead.
