I think it deoends on intended usage. if you are camping in the American desert or Oz outback for a week @ a time and want a starting and house battery then two makes sense. If you are thinking a two battery setup just for normal day to day use, I think that makes little to no sense. In my 130 I run a single Deka AGM battery, the biggest I could get in and out.
Ford super duty diesels use two but this is due to the incredible amp pull that the 8 huge glow plugs use. For a Rover diesel 1/3 the size a single good battery is more than adequate. If you envision needing lots of cranking power I'd look to fix why instead of adding more cranking capacity. Ie if your truck is hard to start it shouldn't be so fix that issue instead.

Consider yourself luck. I definitely replaced more than 12 Optima batteries at the dealership. My statement about Goodyear tires wasn't meant to be about their off road tires. I was more referring to the tires that came on Land Rovers from the factory.

Yeah. I should have said my absurd optima is for the retarded 190 amp draw from the cold start air heater on the mazda diesel engine. 200tdi back in England I used the standard halfords battery and never had an issue starting even in cold in scotland.

I have two northstar batteries hooked up with a hell roaring technologies combiner/isolator, been in the 90 for a year and no problems at all.

The truck starts great. I use the 110 for family camping and have three USB ports installed in the middle row for the kids accessories during the drive to the camping area. While out I do not have a fridge or any devices other than a rear work lamp at the moment. I am not looking for cranking power but more so reliability in the ability to crank. What I am taking from all your info is 1) TDI regardless of temp is good to go with a well charged single battery 2) If I am running any devices (fridge, lots of winch use, electronics) then a dual battery set up with an isolator is my best bet. I am thinking of just staying with a single battery until a true requirement is there for two.

That relay split system up is pretty slick with a on board monitor, seen one in use and they loved it using everything from fridge to laptops n what ever else.
