Since my son was born over a year ago, my husband and I have to drive separate vehicles whenever we travel as a family. This is due to the fact that my Odyssey is a 7 passenger van and we have 6 kids. We are planning a long trip this summer and do not want to have to drive separate vehicles, as it would be cheaper (gas wise) to drive one. His idea is to separate the middle seats into captain seats and place a high back booster in the middle, which would rest on the captain seats and be latched to the system behind the seats. I would like to know if anyone has tried this and if it is even legal to do. Thanks for your help!
