Just to rid you of the sad blue face - I have a tunnel tent that's very similar to yours but am still learning... here's one way to do it. Lay it all flat, loosen the ring and pin webbing, feed in the poles, peg out the rear, loop the rear pole into the pins and peg and peg down, then move on hoop by hoop to the front. Peg out the centre guy at the front and then fiddle around straightening it all out and tighten the webbing as necessary. Some clever people manage to put all the poles in the rings on the ground, peg out the rear then raise it all by using the centre front guy... not tried it myself but I'm sure you'll get lots of other suggestions. You do need more than one pair of hands as in a wind they can be a bit like a barrage balloon. But a great tent, loads of space. Practice makes a perfect pitch, so be patient! Have fun.
Not sure, but I recall a similar question being asked not too long ago .I would say it is as above, but there could well be some horizontal poles to give strength. If you are reading this out there Gelert, pitching videos would be great. Please include all models from the past five years . Plea over.
