Yup. Have to be careful with the zippers and such - not for real heavy use long term - and adding a rain fly (tarp) is a must for wet weather, but if the budget only allows a couple hundred bucks and you need fast and easy, with enough space for adult sized cots plus gear, it's shelter.We have something similar takes one person maybe 5 mins which includes getting it out of the vehicle and its carry bag.
I'm not a fan of tent living either, but from the original post, this sounds like a last ditch, desperation measure more than anything else.
