Don't know that this takes the place of a good tent, but if you want a cheap way to quickly put up a shelter that would be to some degree insulated...
Take this:

but up-size it a bit--you could do uprights of short sections pipe with the arches of 1/2" PEX tubing. Pre-drill holes in the uprights to allow attaching them to dimensional lumber, or do so with pipe clamps. In more extreme cases, lashing them to fallen tree or just to stakes in the ground would be other ways to go. A sheet of visqueen, or a tarp over it, and tacked/stapled in place and you're almost done.
To finish it, winterize it: spray some expanding foam on top of that visqueen/tarp roof, along the arch supports. Hopefully, with someone else to help, lift a second tarp over and settle it gently down on the shelter, so the expanding foam strips don't get too mashed-up/spread around.
The idea is that those stripes of expanding foam will--as they expand--lift/separate the second tarp from the first, so there's a dead air space between the two, for insulation. Also, that foam is VERY sticky, so it should hold that second tarp in place.
That expanding foam could useful in a lot of other ways--to make molded shapes, for one or another purpose, to seal/weatherize, it could be a handy item to have in a B.O.B.
A downside: it's a bit bulky/heavy. Once you used it it starts to harden in the can's spray tube so you can't use the same can over more than a short period (less than a day?). Then again, IIRC nail polish remover/acetone is a solvent for it, so maybe, with some planning, you could get more from one can over a longer period.
Just an idea--been a while since I used the stuff so let me know if this sounds crazy.
And there are better ways to shelter, but this could give another back-up option you could have on hand, for cheap, and store the parts in your garage's rafters, just in case. And if anyone asks, it's a greenhouse kit.
