Although the Mondeo has a max. permissible towload of 1800kg compared to the Jag's 1500kg, it is limited to a max. gross train weight of 3750kg which means that if the Mondeo is fully laden, it effectively has almost the same towload as the Jag.
However, one can put 590kg payload in the Mondeo but only 350kg in the Jag, which is a bit low for an estate. Self-levelling suspension is recommended if the Mondeo is going to used a lot fully laden.
Dynamic towing performance of the Jag is very slightly better because it has a shorter rear overhang.
