I would go again with a v8 Diesel. "Brummie" is a
Toyota Landcruiser 200 V8 4.5 D4D build at 2011.
My car was a bit overloaded near 4to: Fridge, Freezer, 280l Diesel, 85L Water,
Solar and Aux Battery,
heat exchanger (hot shower), food, beer, clothers, i`m able to be self-sufficent for two weeks with that setup..
I did sleep inside for over an year (in severall trips between 2012 - till 2019) , half time with 2 Persons.
My Travelblogs with daily updates and pictures during the trip:
Transafrica:
Trans-Africa
South America:
Adventure-Overland
Just my
Island trip is just a conclusion, did not blog on daily base there
I did use 16.55 liters for 100km during my trips: that is: 7.03612836 gal/100mi (US gallons per 100 miles)
That value I get with a lot offroad and low gear usage, for chilled driving on roads I use 5 gal.
Older Landcruiser probably had less chances for a breakdown, but for spares on your way (Front windshield had to be replaced twice) - they are usually on stock or at the greymarket for the most recent models. Not shure if that would be so easy, if your choosen older landcruiser is not common to be used in a country you are travelling).
Because i did use it as dailydriver between travelling - I did not do a pop-top conversion and cabinetry. What I always regret during travelling and opposit like while working and using it as DD

It still fits in underground car parkings and it is still pretty stealth for sleeping in more crowded areas from time to time.
