The only thing I can think of is if you buy the carpet for the Tigris 600. The only problem with this is the shape of the carpet which will need to be altered. I would suggest you check and compare the dimensions of the 400dlx and 600 first though just to be sure.
i will have a look tomorrow for you but to be honest i think we only do vango and some sunncamp carpets,do you know the measurements of your tent? i might be able to match it up with another tent carpet.
