I've asked this on the camping forum - but I'm going for a mn opinion too!
I've just bought a Maritsa 700, knowing that I would be unable to get hold of a carpet.
There is one that 'almost' fits (the nadina 600 carpet is the right shape but will be smaller in size) Its also £69, which is ok, but still a lot of money when we need to buy other kit. Its pretty big when packed (40 x 24 x24) and space is going to be an issue even with the roofbox.
However, If I don't get it, will I regret not buying one that covers most of my living space?
There is a gelert carpet on sports direct that is only £24.
Its 235 x 320, so still a substantial size. It would fit down the middle of my tent like a runway with about 80cm gap on either side. Having seen pics on this site, and the floorplan of the Atlantis 5, I think the carpet will be tapered (in a similar way to the maritsa) rather than rectangular but I'm not sure. There is spectacularly little information on the carpets themselves. I have no idea how big/small the pack size is either but I'm guessing slightly smaller than the Vango. I have emailed Gelert to ask.
There is also a waterproof backed rug on ebay for £20. Its 220cm x 300 so a bit smaller than the Gelert carpet. Probably lighter too. Possibly wont last though and therefore not worth it?
Please help me make my mind up!
