Van level or tilted whilst stored
Obviously when you occupy your caravan on site, then you level the caravan both left to rights and front to back.
But what about when it is standing (in storage) between uses ?. Level or I'm wondering if a slight tilt would actually be better - I have noticed that water puddles a little on the roof when the caravan is in use when fully levelled. And to date, no problems with water ingress nor damp.
But the silicone seals/joints between the many roof penetrations and the skin of the roof have to withstand prolonged submergence. The rule of thumb for water run off for a patio is 1/4"drop per foot in length - so it seems to me that when storing the caravan then a 6" difference front to back or a few inches left to right would reduce puddling and may extend the life of the numerous roof seals.
Thoughts ?
