There is no such provisos in the manual in the Autotrail requesting that you don’t travel with the table I place as for confusion if you took the time to look at the pictures I have posted it would be self evident what I am complaining about or are you just being argumentativeAre you supposed to travel with the table in place? Most makers advice against.
I'm confused, are you concerned with the seatbelt anchorage itself. Or the lack of super-structure to stop the rear facing seats going forward in a front-on collision
