瑞典采购需求：车顶帐篷，四驱车顶帐篷，越野车顶帐篷，家庭车顶帐篷，自动车顶帐篷，铝合金车顶帐篷

I've been enjoying my roof tent and appreciate its design, but I find that with additional items like a mattress, sleeping bag, and thermal liner, closing it has become quite a challenge. It would be fantastic if there were a way to enhance the interior space of my tent for better convenience. I've noticed that another model features a spacer between the two halves, which really seems like a clever solution. Would it be possible to create a similar adjustment for my tent? Additionally, I'm curious if I can purchase this spacer component separately. Looking forward to your thoughts!
