With our basic 2.7td without Intercooler, on the motorways you had to hold it back, to keep it down to 60 in 5th, with a boat and trailer that weighed in at over two tonne. it was ok on the dual carriage ways, but on hills, once you had to drop down to third you had to hold it all the way, but if you could keep it rolling in fourth, it flew up hills with it too.
I would have been better with the tdi, but it wasn't available when we bought our Mav all those years ago...lol :lol
I guess it depends on what weight you are towing, if you had say, a shifting load like two heavy horses could be more difficult to control, but hey, an LWB Terrano with driver and gear will weigh in at 2 Tonne easily.
Make sure your driving licence covers you for a total rolling weight of over well over 3.5 tonne. The later ones don't unless you have taken an additional test.
