While it's still on my mind, a neighbour on this campsite is towing medium size Lunar Caravan with the above car.
The car is in mid restoration and has a 5000 litre engine under the bonnet. He's converted it to also run on LPG which is becoming difficult to find.
On LPG he is getting the equivalent of 30mpg towing. Using petrol he is getting 10mpg. (20mpg solo).
He's intererested in Eribas and has been for years.
He wants a Puck to tow behind his son's Mini Pickup.
