"the ruff stuff", whats that then ?, rolled fields ? ploughs ? i'll drive any as i have no respect for my motor, they get used as they should, a dogging motor....
the fields are flat, so theres no need to have a monster truck is there, people have been using subaru's for decades, all season...
the only thing that stops them is very boggy fields, when they bottom out, but a "proper 4x4" that weighs twice as much will still sink in even worse....
