How To Operate An Aussie Traveller Caravan Door 

How do you lock the door from inside?

My door won't always lock,it has come open during travel?

But how do you lock the doors from the inside???????

Does the key need to be locked to travel?

How do you adjust them if they don't lock? we are having difficulties in locking our door on our new van, we turn the handle to engage the lock, but it does not engage?? Cheers Les
