We LOVE ours!!!!!
It's like having an extra room in our camper. That's especially true when it rains!!!! We just drop the walls and VOLIA! no more rain. At night we pull the camping chairs and grill into the add-a-room so they don't get wet in case of a possible storm. DH and I love to sit out there in the mornings and have coffee.
We got our first one as a "bonus" with our first camper ( a Viking Popup). The salesperson just went on and on about it. It was about a year later (when the weatherman was calling for rain)
that we decided to give it a try. Now we couldn't camp without it.
It takes about 10 minutes to set up and it all fits neatly into an flat pouch for travel. The only downside at all is that it really does take two people to set it up. DH tried to do it once by himself
.............let's just say it didn't go well.
I hope this helps!!!!
