It is hard to say, but the weight can kill the fun pretty quick...
The Landcruiser 200 V8 Diesel comes stock with 3to in european specifications (14 Airbags and so on, mostly more an Lexus 570 Diesel). Ab beast doing offroading - but there are szenarios where a light rubicon or similar performs better:
- Steep passages of Sand
- Steep passages uphill on slightly wet gras or on gras
We did severall outings at 3,5to (limit of my driving licence and of the car legally) - with a group of cars.
The heavy ones like the Land Cruiser - was always the first who needs the winch. On Sand a poor point , because of anchor points
For Overlanding or Worldtripping the 3.5tons arent easily to keep. We did travel not legal, with near 4 tons through the world.
And we did NOT carry a second Spare Wheel with rim, nothing bigger than 33 tyres, nor rear bar, no rock sliders, nor a hd high jack, no spare parts, no built in toilet That kind of stuff is barely legal for weekend trips.
For travelling abroad this is to add to the weight bill:
Here I did wrote it more detailed together:

We did travel the world (partly) with Standard-Size (?) but overloaded. What did that mean?
- It was not legal
- we was able to go where we want to go mostly
- We was able to cross limited hight and width areas (Tunnels, small Tracks build more for bike riders)
- was able to do serious offroad stuff, mudd, rock, sand.
What was problematic during the way?
- driving the biggest dunes in africa upwards
- driving real steep stuff in the andes, romainia and other points without winching or help or "to find a lighter way up". (on gras, mud, terrain, not stone or tarmac)
- bit more repairs than stock, but just a bit.
If fullsize would have limited my trip? Yes, sometimes.
But it brings also more comfort with it. Consider that you had too to pay other road taxes, get weighed on the road. Guess, if oversized, you should do it right with 12to to or above.
Most Overlanders dont doing hard offroad when beying 500km or more out of any maintenance, We did, we paid with repairds but had fun ;-)
I would go the ultra lightway path, if planning a rebuild. Other guys travel the world by feet. bike - and show is 4x4`s how less it really needs.
For me is Offroading a part of travelling. Most travellers need 4x4 to be able to, but usually dont need it.
Depends on you, as many other stuff.
To clarify: The Landcruiser is with the right suspension able to handle 5to like the Br7 Armored Cruiser like they sold worldwide. We did the AHC Suspension Upgrade and know that the car was build to handle that weight---
