Found my very sophisticated plumbing layout schematic for the new build. :)
"ESP" is the diesel heater (with integral pump).
"E" is the engine.
"Engine" is the 3 way valve for including the engine in the circuit.
"Cal" is the calorifier.
"Bath" is the bathroom radiator.
"House" is the habitat...
You might notice a bleed valve in the top corner of the radiator, next to the outlet fitting in the pic in my first post. This is the highest point in the old circuit. I did put additional bleeds around the circuit, but I doubt they were needed.
The new radiators are similar except the other way...
Our Webasto on/off switch is reachable without getting out of bed :)
Very important feature.......
We don't have the sub zero conditions like some of you guys though.

For central heating, I have no thermostats in the system except for the one in the diesel heater itself that cycles it on/off if the glycol reaches top temperature, just diesel heater on/off and radiator fans on/off (plus speed control on the new one). I do open windows to reduce temperature...
I have been running something like what you have in mind for 7 or 8 years.
I used a Webasto Thermotop E and a Surejust 30L calorifier with twin coils (one for the diesel heater and one for the engine) https://www.surejust.co.uk/30-litre-horizontal-single-coil-surecal-calorifier.
I used 5/8" auto...
I have an OKA which is now 30 years old. It was fitted with a chassis mounted 100L OEM stainless steel water tank.
The OKA chassis is a very stiff ladder frame, but the S/S tank cracked on several occasions until I replaced it with a heavy duty HDPE rotational moulded tank of my own manufacture...
We chlorinate all of our water, including washing water as that can be a source legionnaires disease which can be transmitted to the lungs during a shower.
Finding sodium hypochlorite (the active ingredient in household chlorine bleach) that is not contaminated with other "stuff" is sometimes...
My Warn 16.5Ti can pull frontways, rearways or sideways. :)
And it always points directly to the anchor point so the cable lays up evenly on the drum instead of bunching up on one side.

Fibre glass catwalk. Any width and length that you want.
There is a little under 2T on this piece.
Can be used for bridging which is beyond the capability of most other options.

Mechanical fasteners do cause point loads which can be avoided with adhesives.
I have needed to replace S/S hinge fixings in our 20 year old build truck. Probably due to 200,000+ km of corrugations. I do not expect that with the carbon/kevlar hinge.

Noticed the S/S piano hinge.......
You should know about this.....I am using the 18mm x 1.6mm on my new build for doors and hatches, secured to glass sandwich panel with Plexus MA310 adhesive.

It has many advantages over S/S hinge (many of which will be...
I am about to install this in our expedition vehicle.
It weighs a tad under 30kgs and will replace 400Ah of AGMs that weights over 120kgs.
LiFeO4 is the safest of all the various lithium ion battery chemistries.

It is important to understand that the chassis is a very ridged welded tube ladder frame.
16 or 18 polyurethane blocks 25mm thick are glued directly to the chassis with Plexus 310 2 pack.
Aluminium tube supports are glued to them.
The 23mm fibreglass/PET foam floor is glued to the aluminium...
If you want to protect yourself with statistics, it is not 624 divided by 320 million, it is 624 divided by just the few who are ignorant enough to put themselves at risk.
