It did work well Tom.
I've only met one of these once before, on Gillies Downs, a sheep station on the Eyre Peninsula.
That one is pretty big, as it needs to provide hot water for a full shearing crew morning and night. The first person awake in the morning lights it up, and its usually still warm from the day before.
This smaller one actually took quite a while to heat. There weren't many campers, and most of those who were there had big self contained RV's.
So it had not been lit for some time, there was a lot of stone cold masonry to heat and the weather was wet and cold. But, by ignoring the sign that said light a small fire, and cramming in a fair bit of the wood I brought with me, we got her hot before lunch. I suppose everyone enjoyed a hot shower that night. :)

We drove part way home yesterday, and camped overnight. Woke to a condensation issue this morning. Walls dripping.
Our trailer is vented with high and low vents in each side wall. I have butterflies so I can close them off for travel.
I've always wondered how effective the high/low convection thing was.
I've never had a condensation issue, but I've usually camped by myself with the vents or even a door open, and this is the first time it has rained continuously for the whole trip.
Well, now I know.
If you forget to open the high vents to get the circulation happening, like we did last night, you are going to be damp next day.
The rain stopped for the drive home, which is all paved roads, so I left all the vents open while travelling. By the time I'd driven 3 hours at 55-60 miles per hour, the cabin had dried right out.

I've begun to take steps to address the condensation issue that showed up a couple trips ago.
I built the trailer with framing in place for a fantastic fan, but after a couple years of use, I'm not in favour of cutting a hole in my roof.
So I thought about it for a while and decided that, for those nights when you just have to shut the doors and keep the weather out, I would fit exhaust fans where my existing vents are.
Starting out with just one, a ball bearing computer fan.
I chose one with mounting hole spacing close to the spacing of the screw holes on the vents.
12V DC, naturally.
I cut out a circle of plywood just bigger than the vent, and the right thickness for the fan.
Mounted it so that it i blowing air out, not in. It's not my best work, but it's functional. Still have to get some clips to secure the cable.
It pumps air, though not completely silently. Current draw is ridiculously low - 0.16 amps.
I'll have to do an overnight trip to see how I like it.

Nice solution. New or old fan? Once the bearings go they get noisy but easy to change the whole fan out the way you have done it.

New fan. I searched for one that specified a ball bearing, many are "sleeve bearing", whatever that is.
It is mounted in the front lower vent on my side, so it's the closest vent to my head. If it pumps anywhere near the rated 54 cubic feet per minute, it should simply draw my exhaled moisture away.
I think it will last a while.
I run a computer fan on my biltong box, typically non-stop for a week, so I expect this will last long enough to justify the couple hours of messing about to design and fabricate.
I have a nice batch of biltong on the go at the moment.

Getting ready for a weekend away.
Leaving tomorrow afternoon (Saturday), coming home Monday arvo.
First job, drag the old Yamaha 500 out of the shed.
Put her in first gear and drag her back and forth a couple times whilst holding the lever in, to unglue the clutch plates from each other.
Pump up the tires, use the fencing pliers to turn on the fuel, wriggle the tap back and forth a few times to wet out the gasket and stop the leak.
Set the "choke" and ease her over dead centre with the decompression lever, bring the kickstarter back to the top and give her a decent boot.
She fired up on 2 year old fuel! I forgot myself and did it with thongs (flip flops?) on my feet. No damage.
Good omen for the trip away I hope.
Loaded her up in the dark tonight.
Tomorrow reserved for stocking the camper, fuelling the truck and hitting the road.

Didn't take a lot of pictures of my weekend away.
The view out the cabin door last Sunday at 4 am was kinda memorable.

When I travel toward the Barossa Valley, the little town of Tarlee on the Gilbert River always figures in my plans.
They offer donation based RV camping, around the old footy oval.
And the pub, built in 1869, is a great place to socialise and eat.
I planned to camp and eat on Saturday night.
Which provided a second photo.
When I was a kid in the 1960's, a staple of the hotel counter meal menu was the humble ham steak and pineapple.
The epitome of "cheap and cheerful", and something us kids always looked forward to whenever Mum and Dad decided we could afford a night out for dinner.
So when I set up camp and wandered up to the pub to see what was for dinner, I was much impressed to see it on the specials blackboard.
Talk about a blast from the past - you very seldom see it anymore.

Two thick slices of grilled ham, topped with slices of grilled pineapple, and melted cheddar cheese over. Served with good hot chips and a very good salad.
A proper old fashioned pub meal, served at the bar and eaten on the counter, like the good old days.
In this era of $40 steak dinners and $30 schnitzels, the other blast from the past was the price. $18 in this day and age is a steal.
I celebrated the unexpected boost to the budget by staying to watch the game (Australia v New Zealand) and have a couple of pints.
