Caravan with long drawbar searched

Since it is slowly approaching retirement, I would like to extend our pickup with a cabin with a caravan to the double room for longer and more comfortable trips. It is stupid that the cabin extends beyond the loading area and covers the tailgate. From the center of the head of the ball to the left or right outer corner of the cabin I measured today 1.15m. With this, caravans such as the Eriba Touring and the cabin touch each other in narrow curves. For a test over Easter, whether we as previously convinced sideways and offroad drivers can even make friends with it, I would like to borrow a caravan first. Therefore, the question to the forum, whether you can call me caravans that have a sufficiently long drawbar. I think 1.30m should be enough. Perhaps 1.20m, if the caravan has a strongly inclined front. And if you still know a rental in the Ruhr area, which offers this caravan, it would be perfect. In the attachment a picture of the PU with a cabin from the side, that shows the overhang and the massive corner, are attached to the supports, if I want to take away the housing cabin.
