Albin Vega 27 on diet - reducing weight for trailer

[Saby]

A swiss family has towed their Albin Vega from Switzerland to the French Riviera (>700km) and at the end of their journey back from Venice, Italy to Switzerland again (>600km). They used a Jeep Grand Cherokee, not sure what engine but I think it has a towing capacity of 3'360 kg, and a 2 axe trailer.
Their website is www.aliki.ch and there is a picture of the car with the trailer and the vega on it here: https://www.aliki.ch/reise-2007?ligh...aItem-k4on57kq
From that I conclude it is doable if you are careful, but I wouldn't want to do it on a regular basis for sure.
