Need both ends out?

It wasn't a Coleman but opened now and then when we had a popup.

If it was really windy you might have a problem with the tent panels flapping around too much and cause damage to them. Otherwise I don't see a problem. However if the front bed is in and the rear bed out I'd deploy the rear stabalizers. I had my Coleman set up in the front yard airing out and getting ready for a trip. I had taken storage totes I kept loaded in the trailer off the floor and placed them on the rear bed so I could open some side cabinet doors. Later I climbed on the rear bed to unzip the rear tent window. With my weight of just over 300 lbs and the added weight of the totes I almost flipped the trailer. I came flying off that bed. Never did that again without the stabilizers down.

Do what mobeewan said. I did the same thing once. Had to manually lift one end of the roof to do some repair. Had two neighbors help me out and when all three of us got in, we tipped the trailer. No damage done and it ended up being pretty funny. If you are working on the back end, make sure you put down the stabilizers. If working on the front end, the tongue jack will be enough.

There is no reason to be concerned about only having 1 bunk out. How I have to park in my driveway, we can only partially put out the back bunk and have never had a problem.

In my area we get severe storms year round and winds can exceed 80 mph any day of the week. If pup is stage or partialy setup excessive damage can occur. I pop the entire unit and have it setup fully for any repairs/cleaning.
