We have an Dometic RM2555 150lt Fridge Freezer, normally running on No2 setting - 9kg bottle normally lasts us 4-6 weeks it depends on how much we use internal stove/BBQ/Hot water and whether we are travelling or Free camping - It basically boils down to ambient temperature - how often fridge is opened - and how full is fridge (ours is always crammed full - Child bride likes her wine chilled).

That fridge won't hold much of the good drop mate.

You should get a couple of weeks I reckon. I get 13 days with my 180lt Thetford.

Yep about 14/15 days thats cooking fridge and heating the water any more than thats a bonus

2 to 4 weeks here Under say ? 24* lasts 3 to 4 weeks. Over 25* it uses way more . Mind you we're possibly using the fridge more ? The 60 litre portable 12/240v comes in handy in hotter climates . Fridge is just a storage compartment ..

On a normal bush camp using gas on both fridge and hot water service plus cooking etc 3 weeks per 9kg bottle when the temps are below 30c.

When the temps are above 30c during the day then it reduces to approx 17 days. Which I might add suits us ok.
