motorhomes and car seats ... getting worried!

[tomate]

Hi, we are travelling for a couple of weeks in a motorhome with 2 little ones (2 and 4) and I am beginning to worry about car seats. There are two lap belts and one three-point, but this one has an airbag which you can't disable. I know you can get lap belt car seats but it seems only one seat has a tether/ latch to attach a car seat. Surely we can't be the only people ever to have taken little ones in a campervan?! (It's a C25 if that helps...) (Have also posted general travel thread).

should have said hire company doesn't rent them but said we could buy/ rent seats nearby

we travelled in a motorhome in Florida last summer with three kids aged 15, 12 & 21 months. Pretty sure it was a C25 and in addition to the normal front row of seats in the cab there were seats both sides of the table in the back and one immediately behind the front passenger seat where we managed to strap in DD's car seat. Her seat also fitted in in front of the table which was quite handy for eating on the go or drawing etc.
DD loved sitting in the back and the bigger kids sat back with her and entertained her. We took our own car seat as they are so expensive to hire out there. Friends of ours are going this summer for 3 weeks and have been quoted approx £175 to hire one car seat!
