Hi, there are many models of Monedo estate with differing kerbweights and towing specifications. The issue with the towbar height should not be a problem as all Type Approved towbars have to conform to a set height range. Thats the same for towing a single or twin axle van. What you really need to do is check out the car's kerb weight, its maximum towed weight, gross train weight, and the caravan MTPLM. For someone new to towing caravan the advice is that the MTPLM of the caravan should be within 85% of the car's kerb weight or less. Many car makers quote a towed weight far higher than should be actually towed as it relates to the cars ability to restart on a defined gradient. Hence the 85% guidance. What type of licence do you have. You should check whether it allows you to tow an outfit of above 3500kg, or less than 3500kg. And the 3500kg is the sum of the car's gross weight, or maximum authorised mass, and the caravans MTPLM. Its not what they actually weigh its what they are plated at.
I have had two Mondeo estates and they were fine tow cars, and later models are too. But you have to stick within the limits and the law.
