Hiya
Sorry to ressurect an old(ish) post and hope that this is still relevant... or at least of use to someone!
We have a F2 that is nearing 3 years old - originally bought for the Fun Prevention Officer with a view to her being able to cart around the country and tow a horse trailer periodically.
As is the way with such things, she has been in and out of wet fields, ruts, long wet grass and, of course, the snow that we had last winter... the TR coped with everything we asked of it.
This included a hill start on long wet grass, on 95% road biased tyres with two ponies in the 'box... probably getting rather close to the 2 tonne mark!! [-X
The chap with the tractor who was earning a few quid here and there for towing people out was most miffed...
In my mind, worth every penny although some might argue that 'standard' four wheel drive would also have been good enough.
Hope this helps
