We had ordered a Gordigear Roof Tent Explorer Plus including annex (http://www.gordigear.com/roof_tents/ext_roof_tent.php?l=en).
It arrived less than a week later.
But, ¡¡¡OH MY GOD!!!, the thing is huge and very, very heavy. Nevertheless, with the help of a pile of wooden pallets we (Norbert and I) managed to put the thing on top of our car..
NOTE: In order to comfortably and safely mount the tent it takes at least 2 or 3 strong guys!! 45 kg may not sound much, but it’s hell lifting it up a 2 m high roof top.
