We have had our pvc for a year now and we're discussing if there was anything we would change. We decided on the layout after having two previous vans and really thought long and hard. However if we did it again we would not have a double swivel seat, just single. At the time of design, we didn't have our sons dog permanently, so she was factored in as an occasional not full time. We thought five seats with straps was pretty important, but in practice have not taken our son and his family away in the van since we gave them our old one so we go in convoy! There are always tweaks which you want to do, but maybe our experience may make someone else think!
