Anyone with zipper problems? Loving my James Baroud Grand Raid XXL as well and my fan is also starting to make some noise. Purchased in 2014, I'd say, I had spent about 30 days total in it (which is about to change going forward).
My zipper is so tight around the doors, it takes both pulls and both my hands to get it down/up. I had broken-in the passenger side door as it's my main ingress/egress. The driver's side is above my awning so I rarely use it.
Recently, I wanted to vent my tent and opened both doors. I noticed that the zipper from the driver's side tent entry popped open behind the zipper head by about an inch (it just busted open).
I wasn't able to zip in reverse past this opening to open the driver's side tent door. I had to brute force it to go past. We are talking about 40+ pounds of force. Also resorted in using a flathead screwdriver to pry one side and the zipper head is pretty solid. Now, the teeth mesh together but at different angles; it should be flat. This means that with enough force from winds, it busts open the zipper again.
I have no idea how to fix this and it seems like a function of the zipper head.
The 'taughtness' of the fabric is great for windy situations but in my case, it seems like it may had put too much strain on the zippers to the driver's side door and I may have had a manufacturer's defect. Had I worked on this earlier, it would had been under warranty.
