From the outside this looks like a deceptively simple unit but this mobile workshop was a very complex build and took 8 months to complete. It arrived as a bare cab and chassis. It now has a walk-in workshop kitted our with a hydraulic ram, crimping tools and all the gear for installing, repairing and servicing hydraulics. There's a full custom built lube station with individual storage tanks and lines for oil, brake fluids, hydraulic oils etc. You'll also find generators on board.
As you can see there's plenty of external lockable storage for tools and parts, a pal-finger hi-ab and even a workbench / platform with vices etc.
It's been well thought out so that Garton's can effectively roll up to a breakdown or work site and fix the job then and there.
