Welcome to the whacky world of caravanning and the mad house referred to as a caravan forum. We had a caravan, then went to a motor home and now back with a caravn. the reason we came back to a caravan is that with a 13 year old grand daughter she reckoned there was not enough privacy in the motor home for her to dress/undress, etc.
Well done to both you and your wife for the great work and responsibilty of being foster parents. It is something which I admire in any person taking on the care of a young person with limited history of the child's previous life, both social and medical. All I can say is keep up the good work and I will take my hat off to you.
