So why make out you didn't ? - If you were familar with the regs and requirements of moving heavy loads around, why question it ?
FWIW, I looked at getting Subaru Forester as a towing vehicle, but it simply wasn't heavy enough. In addition to this, the transmission is AWD as opposed to 4WD which means that it is a lot less capable coping with low traction conditions like my car which has deep and wide tread,pattern all terrain tyres, auto locking hubs as well as an LSD on the back axle, and a centre locking differential to the front.
Hill farmers run tractors as well as their little pickups as they don't need to transport their animals to events 30 miles up the motorway at the weeekends.
The vehicle is fit for purpose at the end of the day, and if the hill farmers needed a bigger one, I have no doubht they would just go and get one....
