Carthago - to go

This week's shipment of campers and mortorhomes from Europe included at least half a dozen vehices, but the only one I saw outside the fence was this luxe version that would definitel;y be in the mini-motor home categoary.
A slightly used BLB pie will be awarded to the person who can tell me what commercial truck chassis is used by Carthago to build their vehicles.
No fair peaking at http://www.carthago.com/ for the answer (although I doubt you will find it there - I didn't)
