very large tent with leaky porch (Hillfields BS16)

This is an Easy Camp Wichita 400, a large tent with a porch and a sleeping area.

The sleeping area is 215cm x 240cm, with a divider that can be zipped into place to split it into two bedrooms 215cm x 120cm each if you prefer. Plus a sizable porch.

NB I haven't tested this tent (got it from a friend and never got around to using it because it's much bigger than I need), but I lent it to another friend, who told me afterwards that the porch area leaked, but that the bedroom/sleeping compartment did not leak.

Hopefully this is a problem that can be fixed by re-waterproofing the tent? Or ignored if it doesn't affect the bedroom area?

If you search online for Easy Camp Wichita 400 you can find reviews, youtube videos giving a good overview of the tent and its features.

Note that the photo I've attached here is a generic photo of this model of tent from the web - the tent is quite large, so putting it up to take photos is a significant effort. But I would be happy to do that - ie put the tent up to test that all the parts are there (and take photos) - once I know there is someone potentially interested.
