I'm a proud owner of one of your rooftop tents and I'm in need of a replacement outer fly. Could you let me know if this part can be purchased separately? Additionally, I'd appreciate info on pricing for the fly, as well as shipping costs and estimated delivery time to Malaysia. Looking forward to your prompt reply so I can get my tent ready for future adventures!
