The condition is very, very good. it has only been used a few times for camping in Scotland, Wales etc and for a two week trip to Bosnia.
I can not remember the exact sizes, but it is the XL one!! I am 6ft 5 and felt that the bigger size would be thebest option!!
They retail new for approx £650 then fitting etc is on top (approx £50.)
I have used ut on top of my Range Rover, and it fits really well into the gutter rails. It takes about three minutes to get it fully opened and you inside (I know, I Put it up in the pi**ing rain in Bosnia). The matress is excellent, there are inside pockets etc and it is very well made. Overall an excellent piece of kit, but we no longer have the Rangie and we are planning to move to South Africa next year, so every penny counts!!
