Hi Adrian
I have a Pajero 2.5td auto swb and it tows my t/a Abbey Vogue with no bother. I'd go for the 2.8 if I was buying another one simply because of the chain camshaft drive belt.
Pajero's are reliable but can be very thirsty, around 20mpg towing and 24mpg solo around towns. This improves to around 28mpg solo on a steady motorway run.
Some insurance companies try to load the premiums and state that parts are difficult to come by because Paj's are imported but that is bunkum. There are specialist insurers such as 2gether in Ely who charge normal premiums.
The cars are very reliable and at the moment it's a buyers market so look for a Paj with cruise control, heated leather seats etc and there are plenty to choose from.
