I own andamp; operate a 4WD as it is the only vehicle that can legally tow my caravan. In addition to the above reason I would point out that I get better economy then most travellers that are towing smaller caravans with their Petrol CARS! I consider that It doesn’t really matter what type of vehicle a person is driving, The main things relating to both safety and economy, ALL depend on the Experience, maturity and attitude of the vehicles driver! (Some people just seem to be born with a “short fuse” and have absolutely no consideration to other road uses.)
