Brake Lines Blown While Towing with Toyota Tundra!!!!

1st glad you and your family are ok! You just lived through what I would consider the most scary experiance an RVer fears which is loss of brakes. You were lucky you had the ability and space to slow the camper down with the trailer brakes.

2nd I do not think you will get anything from Toyota other then getting it fixed under warranty if it applies. Unless it is happening a lot with these trucks and they admit to a failure through recall, even then I don't think you will get anything.
