We have worked on Marco Polo and while nice vans, a few things I was surprised at. 1, no insulation behind the lower unit, just a water tank against outside metal skin… Shelving etc. very flimsy, many bare edges on show. not much storage. The rear seat folded independently, good idea but they were easily mis aligned and then needed aligning. The factory ones are all probably the same I suppose. I still think a good converter can do a better job workmanship wise.
