I look at the counter top in the kitchen of the moho and do not see any sealant at all between the top and the wall of the van or the lounge seating. This makes me think that the water that inevitably splashes around while washing dishes could creep down the gap and eventually cause problems with damp. The same in the bathroom where the wash basin is. Is this normal in our very expensive vans? Do you guys/girls add sealant yourselves, for example silicone?
