What I do when I have to set up or take down a tent in the rain is to put up my pop-up dinning fly. I have a 12 X 12 foot one that has the fabric on the frame and all you do is extend the poles and it’s up in under 30-seconds. Put the tent up under this and you have no problem with rain in the tent. You can buy a pop-up dinning fly for $70.00, well worth the price. I also bought a bug screen I can attach if needed, turning it into a bug free zone in the evening.
