We've been looking at vans either 5 or 6 birth and have come across the bunks over side dinette's that are on a metal frame and look quite sturdy but others where the bunk is over a double end dinette area and you have to lift the bunk down and it rests on blocks on each side of the vans. This looks very narrow and not safe and as we've an 11 year old, do you think this format is too small? Will it also become a pain putting the bunk up each night? Help... we want to buy soon but cannot decide which layout to go for. Can you share some of your realistic experiences? Thanks....
