@AdamChandler, bit late on the reply, have been riding! Getting some miles in before it hits subzero temperatures. No chance water will come in the floor, the floor fabric is 190T Nylon, an ultralight, Rip-stop fabric with a 10 000mm waterproof coating. The seams are taped too. There is an SOS groundsheet thats is a must in my view. With extended use without the groundsheet (Also made from 190T Nylon with a 10 000mm waterproof coating) dirt and dust embeds into the fabric without regular care reducing the tents lifespan. Look after it and it will last a lifetime. The floor fabric comes up a few feet too, that stops water getting in from splashbacks and makes the tent warmer. I learned the hard way on cold desert nights and in Northen Europe. The ADVTent is already 20% off, so it couldn't be included in the BFCM sale, Pre-order will come with a free groundsheet, shipping, and an awning kit. So you can attach the door to the bike or something else for outdoor protection. Years of ADV riding and camping experience have gone into this tent, its a lot of fun designing the dream tent I wished to have on all ADV trips around the world. Going to come out awesome. Should be shipping in a few months!
