Some time ago I discovered the Unicat website and the vehicles that they build: http://www.unicatamericas.com. After a quick check of my bank account it became obvious that the only way to ever have one of these trucks is to build it in Ror...
And because in Ror anything is possible I skipped the option to build a small Unimog 4x4 or International 6x6 and directly picked a huge 8x8 truck. The basis was Cadillac84s Oshkosh LVRS. The truck was rebuilt into an Oshkosh HEMMT-A3. The 5th axle was chopped off and the solid axles were replaced by an independent suspension system (Oshkosh calls this TAK-4 suspension). It comes with a big 500hp engine and a 7-speed Allison automatic gearbox.
The truck is equipped with 2 air condition units, heaters, solar panels, 2 spare tires, etc. Everything you will ever need to survive. See the Unicat website for details on what options are available for these type of trucks.
