Easton Rimrock 1 Tent

Ordered one of these when they first came out and returned it.
It was quite heavy and had the so-called catenary cut floor, which made the small floor area even smaller. A BPL review of a tent with this type of floor stated that the floor collected wind and rain water underneath the occupant – not pleasant. The material is polyester, so at least sag would be limited.
I think there are better tents of this type, such as the Luxe Firefly and the Sea to Summit Bug Dome. REI also sold a dome bug tent with the poles that cross twice. Cheap versions of tents of this type are sometimes sold by Sportsmans Guide. Searches of the European companies might bring up others. EMS had a nice solo tent of this type, but discontinued it – called the moon shadow.
You might try a PM to Franco for possible others.

Couldn’t help but notice that the specs given in the mfg. page were wrong.  Never a good sign.

Thank you. What is the exact problem with the floor?

I was thinking about is a cheap tent which can hold against major winds.

A “catenary” floor, using the term in the BPL review, does not have a perimeter that is held tightly to the ground. Even under a protective fly, wind, rainwater, snow, sand, or whatever, will find their way under the floor. Especially in those major winds you mention.
You will get soaked, asphixiated, and/or blown away, depending on the weather.
Also, almost none of the ‘cheap’ tents pitch the fly before or together with the inner.
In severe wind (or rain), it can be extremely difficult to impossible to get the tent pitched.
Also, for some reason doublecross tents, like tunnels, are unfortunately made much heavier, probably because the design is intended for severe weather, so they use extra strong (and heavy) materials.
The cheapest tents, a la Walmart, are not the Dupont 6,6 nylon that is quite strong.
For a very light tent that is not a doublecross, but should perform well in the wind for its weight, you might consider the Nordisk Telemark, which comes in several different sizes and material weights. When you get down to 7-15 denier nylon (not the weaker polyester on the Rimrock), there is a risk of severe wind tearing the tent apart. For the adverse weather you speak of, 20 denier or higher is less risky, and the upper portions of the tent should be well guyed to keep it from blowing about or flat.
I have a cheap doublecross tent from Sportsman’s guide that I bought just for the pattern, but have since moved on to better patterns. You are welcome PM me WITH AN EMAIL FOR REPLY if you are set on such a tent, however.
A cheap tent that can withstand severe winds is a nonsequitur in my opinion.
