You can tow it with a car
Not all Australian Touring Caravans weigh 8000lb, there are lightweight single axle models, like this 4,200lb , 22ft version that can be easily towed by a car.

As Robert wrote many Australian sedans used for towing with no problem but most use a 4+4 pickup or station van. most vehicles are limited to 3500kg tov capasety or les and no more than 10% on towbar. I don't think it is anymore dangers using a car than a truck as long as u stay witin its ratingd. not everybody neds a diesel dually so grow op.
