You could roll up on the campsite looking like a delivery driver, run down to the back, kick the veranda down and appear as Samedy Sam
I think the bit in the blurb about not wanting to be reminded they're in a vehicle needs some believing!
The 6x6 Pinzgauers are nice we travelled with a Swiss couple who had one but AFAIK they only come in Petrol. We met Dutch couple who had a Unimog camper, 80kmph max from Holland then the clutch went as soon as they hit the desert, after a month waiting for a new clutch they gave up on their trip and turned for home only to lose the clutch again We also met a French family in a huge 4x4 Man camper which was stuck in the desert for a week because none of the local trucks could pull the beast out, they had a huge winch but what do you winch off. On the other side we met a French family in a Renault 4 who didn't seem to have any problems
