Any ideas you have from your troopie experiences i'd be glad to chew on.

Gday 61Mk+,
It seems like you’ve thought of everything… it took me a large number of hours to get through the post just looking at the pictures and a bit of text so I haven’t read absolutely every detail. The only thing I can think of that I didn’t see was reinforcing of the chassis and body mounts, and an engine-run hot water shower, the latter my missus absolutely adores, and well I’d be a liar if I didn’t say it’s also grown on me… nothing like sitting by the fire with a beer and steak after a steaming hot shower! You probably got this in mind though, but you’ll need to plan a space and weld up a mount. Mine goes behind the front left headlight.
But about the reinforcing, while the 70 series are tough, fully loaded at well over 3 tons is another story. For example, my troopy gets loaded to the gills and already has about same amount of perimeter steelwork as yours. Whilst recently driving around in dunes fully loaded at low speed, I went straight over a blind drop on what was visibly on either side an easy 1.2m slope at 45 degrees. Hitting straight on the only vehicle-width spot with a 1m straight drop in 3rd low, the steel bullbar hit ground first, she bounced up and on and I destroyed one of the rear tyres on the rim as they came over (were at 12psi). Bear in mind I have extra heavy duty 2” TJM suspension all around which was unscathed. At first I thought I’d twisted the chassis, but in fact what happened was the cabin section (with all the weight) lurched forward on its body mounts (by about 2”), hitting the front panel section at the bottom of the windscreen, putting a massive fold in the top-middle of the mudguard panel beside the hood, as well as taking bark of all the panel joints and prohibiting me opening the passenger side door. There was obviously a deal of chassis flex in there over the length of the long wheelbase on the first impact contributing to the collision of body sections at an angle, but these had returned to normal when measured at the panel shop.
Now I give my troopy a good run for her money, but I’m definitely not an overly aggressive driver and I don’t consider my misfortune to have been particularly extreme at all, and I can imagine much more forceful offroad situations by anyone slightly more aggressive than myself. So with tons of weight onboard and the intention of not being kind and gentle as you say, I would definitely think about doing some reinforcing here and there to make her more robust at 3.5-4 tons (to be able to resist say getting slightly airborne), as they definitely aren’t built like the 40 series. Don’t ask me how to do it, I’m no engineer and I haven’t done it myself, but after my recent experience I would go all out if I ever stripped her naked. Anyone who’s prepared a TLC for racing would know what to do.
Look forward to seeing how you deck out the inside... that's where you can really start to get pedantic!
Cheers,
