I have a Marmot Limelight and last time we went camping in the wet, we did get some water inside the tent even with a footprint. It was quite rainy and the ground was muddy, puddly lawn at a campsite. The tent is a 3p tent, so it has a seam on the floor and it looks like the seam tape is coming off. Marmot seem to have lifetime warranty. This is from their European website: Manufacturing and material faults are covered by the (lifetime) warranty. The term ‘materials’ includes fabrics, buckles / fasteners and zippers. The term ‘manufacturing’ includes seams, seam taping and the material’s coating or finish. Does this look like it's maybe not waterproof anymore?
