About a year ago I was given a three person dual skin popup tent. Almost new but possibly a factory second.
(It's made by "Vango" and I think it could be a "reject" because one of the four guy ropes is not attached to the tent and looks like it didn't get ripped off but was never attached.)
Anyway it's a great tent and I have used it on a grassy area, properly pegged, in reasonably solid rain with 3 people and luggage with minimal wetness.
But now I'm camping wild at the beach and water has made it into the tent twice, always from one of the corners.
When I first set it up on the beach instead of trying to use the pegs I weighed it down with rocks inside between the inner and outer skins. (The standard pegs are heavy duty enough for dry sand and windy conditions and I was too lazy to use sand-filled plastic bottles instead of pegs.)
Another factor is the sand was on a bit of a slope so I dug down a bit at the back and used that sand to build up the front, thus making the area flat but the rear is a bit like a trench and also it's not a perfect fit for the tent. Some corners are a bit outside the flat part and the rocks between the skins could slide down a bit, especially when there's some rain, wind, or both.
When I added the tent pegs and guy ropes after the first storm, because they weren't very deep, I dug down a little so the pegs would hold better, put a rock on top to weigh them down, and covered them with a pile of packed sand. In some places I may have heaped a bit of sand over the lower edge of the tent wall too.
- Were the rocks between the skins the cause of rain getting in at the corners?
- Or possibly the imperfect fit in my dug out slope?
- Or possibly having some sand piled on the tend walls? (not much)
- Or are all of these factors usually no problem thus pointing to more possible manufacturing defects?
- Or maybe Vango is known to be an inferior brand of tent?
Are there some general "dos and don'ts" for setting up a dual skin tents or popup tents or tents on sloping sand?
