I have found several resources online, that have tables outlining all states in one place. AAA has one, and there are others.
I have found though that the booster seats don't really work all that well in the RV.....and in some way things look better without.
Sideways facing seats
dinette seats with the table (aka head knocker) right in front & restricting the added height from the seat, etc.... just aren't meant for use with child restraints.
