First thank you for your answers, it is really useful to read different opinions and American points of view
so I do not know if Ron has changed something in the width, anyway 30" at the foot will still fit
as for the Solplex, that is an interesting tent but the width is only 30" head to foot that is not enough and I am afraid the door could flap because there is no zipper
I am sure you know these tents very well, but I would say the Skyscape is easier to set up because there are only 5 pegs, there are 10 for the Hexamid solo plus (in a rocky ground it could be a hard job!)
the skyscape X is lighter .15 + 5 pegs versus .16 + 10 pegs
the problem with cuben shelter is that it is so expensive that you are afraid of buying the wrong one!
read you soon!
