Snow, Ice, and slide outs?

Our brand new fifth wheel is sitting outside until I can cut some more of the loft out of the barn. It's just a little longer than our old tow behind. The problem is we have nasty weather coming our way. I had all the slides out as we've been showing her off and putting all our stuff away in the new trailer. Just to be safe I thought I should pull all the slides in tonight. They don't have the awnings on the slides like out old trailer did and I didn't know if they could be left out or not. I assume they leave them out at the dealership, but I didn't want to chance it on my baby. Did I do right? Or did I over react?
