Jimny Heating and other camping gear

After spending a weekend sleeping in the car I have been thinking about doing more of it.
I was so surprised to find that sleeping in the car was great!
So i have allready plans for making a fold-down shelf on the tailgate, getting a better mattress, lights inside, 12v connection in the back++



But Norway can get cold. Very cold.
My winter sleeping bag have kept me warm in a self dug snow cave and snowed in tents and even outside in the winter in the mountains.
But that is more like staying alive and not particularly comfy.
Wool clothing and good shoes and all is of course obligatory.
Also in wet weather some sort of heating would be nice.

I have been looking at different heater solutions and of course a webasto or ebersprächer is the best option.
But expensive and maybe a bit overkill for a small jimny.
I allready have installed DEFA electric heater both for the engine block and a fan for the inside but they need 230v outlet.
Butane and propane systems are a bit hazardous and produce condensation. and too big.

Is there any heating system i have overlooked?

Other camping tips?

I have a made in china ebay copy of a ebersprächer heater, its a 2kw diesel version and has variable heat output. It cost me £400 with the install kit and its been great. It heats my small caravan and tent with not issues and is a number of years old and still going strong.
I did have to fit the optional exhaust and inlet silencers as it sounds like a jet engine when running without these.
A friend has one on his Series Land Rover also which he uses to heat it when he sleeps in the back.
You are going to need a small diesel tank and maybe a split or larger battery to keep the 12v fan running all night.

I have had two VW's (T4 and T5) with webasto wich both have had the need for servicing so i know those systems pretty well.
Still think they are overkill both in sence of what space they need and how much heat they can produce. Got an extra battery in my VW T5 now.
Great system with radio remote as well.
Agreed they need both silencers and an extra battery
Had to change a rusted silencer on my old T4 Webasto and the burner. Changed the combustion fan on my T5.
No problem to fix them once you get them out of the cars.
Would rather have a diesel burner and the extra tank than the gas version.

But still i would like something smaller i think, how big is your heater physically approx.?

I wonder if there is a way you can use the existing cabin fan and heater matrix, and add an auxillary water heater in the engine bay? That way you remove the issues with condensation, and save a lot of space. You would however need some kind of water heater, a small pump and an auxillary battery to run it.

I do lots of winter camping, often travelling by motorcycle, so I am forced to take the alternative approach of insulating my body with sufficient clothing that I do not rely on any other heat source. It is a different sort of challenge, but I love the feeling of being toasty and warm whilst still being fully exposed to the environment.

Yakuza .....My heater is approximately 110 x 110 x 350mm, going from memory. Dont think its going to be smaller as its a china rip off of a webasto 2000 stc diesel heater...

Busta.....you can get engine preheaters that keep the water warm, but the draw a few amps and are more suited to a mains hookup or generator.

When I had my 3 door discovery I had a separate leisure battery and 4 of those cheap ceramic heater things in various places in the cabin. Even in what passes for winter in the UK I never needed more than a summer sleeping bag and mostly that was overkill.
