[Goin 4 Broke]

Tried to pull in the Main slides and the kitchen slide top gets stuck such that the bottom tries to continue in causing a way lopsided wall. We put the slide back out (it had only come in 3-4 inches) and I can see 2" think ice /snow on top.

We fired up the furnace and I will try again tomorrow.

Any advice on removing the ice slabs?
