Do I need a stabiliser to tow a 2 berth caravan on the motorway.
Stabilisers are not a legal requirement. However, they are are really good idea and I would never tow without one. Motorway towing can be a bit daunting for the inexperienced, especially when you are overtaken by lorries. The draft that they create after they have passed can make the caravan sway from side to side and having a stabiliser fitted does help counter act this some what. I found that the smaller the caravan I towed, the worse it was.
