Child Seats in a Bailey Advance

I was looking at our Hymer in respect of putting our 3 year old granddaughters seat in. That also has the isofix latches for her dads car. As well as the seat belt through the back there is also a strap, that in our Xtrail goes over the back of the seat and clips to one of the cargo securing hooks on the floor of the boot area. This then holds the seat very rigid, without it as you mention it feels unsteady. Unfortunately there is no way of utilising the strap in our Hymer. So for the moment, when we get round to taking her (she keeps asking) we will just stay local and also take the car.

not all car seats have extra straps though. I know the strap you're talking about, one of my grand daughter's previous seats had a strap that anchored behind. Her current seat just uses the car's belt ie she sits in the seat, there's a guide to hold the belt over her shoulder & she uses the belt as normal. I do agree that clipping in the isofix holds the seat itself more securely

We just been given such a seat. It wouldn’t be suitable for a very young child. I think the suggested minimum age is 4. However, at 3 years and 8 months our grandaughter is as tall as many 5 year olds, so it should fit perfectly. Looking at it there should not be a problem mounting in the MH.
