I am back with another caravan and hopefully changing the car but getting all confused but it doesnt take much! I am looking at gettting an Audi A4 2.0 TDI Quattro and the unladen weight is 1595kg but in the book it says the mas trailer load at 8% is 1900, the unladen weight of caravan is 1217kg so wondering if this isnt a good match, be grateful for any advice, thanks
1900kg on an 8% hill is the max weight the car is technically capable of towing but it does not mean that is a sensible weight to actually tow. If your caravan has unladen weight of 1217kg then it probably has max weight of around 1400kg so a reasonable match for your car.
My previous tow car was an A4 2.0TDI Diesel. Really economical getting over 32mpg towing although mine wasn't a Quattro. We towed a 1275 Bailey which was a bit too heavy but it coped quite well.
