"Also, before you spend your hard earned on a D3 - try a newer Tdci Defender with a 6 speed box- still a higher tech CRD, but the few sensors the Tdci has are generally a lot less prone to off road damage and theres a lot less electrical gubbins to go wrong on the rest of the truck.

That may be a better compromise.

You can also put a brew or a bottle of on the wing without it sliding off.....[/quote]

Being a Land Rover Mechanic (not franchised!) I'd go for a Disco 3 over a Tdci (Puma) 110 any day. Ask an AA relay driver which white van he picks up most often - Ford Transit with this engine! You can put your , brew, next 10 days rations etc on the wing of the 110 while you work out how to bleed the fuel system when you change the filter. Great! If you're going electric, "in for a penny, in for a pound" as they say. At least be comfortable. If you're slightly taller than average, the 110 dash will make your kneecaps ache on bumpy roads! (Sit in one and see what I mean)
On a short trip, in countries with relatively small distances between settlements and reasonable infrastructure, any well serviced car should see you fine (except a Td5, which I wouldn't take to the shops!) although there's an interesting post about low sulphur diesel elsewhere on the forum. Other than this, the discussion about the most suitable vehicle at this level is, in my opinion, largely academic.
