Can we use a child seat in the camper?

All models have full airbag control but child seats can only be used with the three-point seat belts – we do not have ISOFIX. Please note in our family sized campervans i.e. Easy Viking 4×4, Easy Viking 4×4 X, Easy Big and Easy Big X child seats must be put in the front seat as the back seats have two-point seat belts!
