Mine seemed to be pretty water tight, didn't have it long though. Sold it to my cousin and he uses the snot out of it and hasn't mentioned any leaks. The windows were a tinted plastic that zipped up with netting on the outside if you wanted natural climate control. Seems like there was a canvas flap that would roll down to cove rthe windows for privacy. The canvas can be replaced if its worn.

I also had to set my mast on the trailer just right so it didn't hit the camper, basically it couldn't extend past the trailer tongue. Have to do the same with my RV.
