Initially as per the caption I thought it was Australian but it is only Australian engineered?I would just point out that its an American video, and although it's referred to as "An RV", in UK terminology it's what we call "A caravan"
At 1:04 you see the front of it, at 1:56 theres the towing hitch, and at 7:57 it's shown hitched up to a pickup truck!
