Door issues

Is it setup? And if so, Do you have it sitting on the stabilizers instead of the wheels? In other words. Did you use the jacks to lift one side to make it level. Instead of raising it with blocks under the wheels? If that is the case. You could have put the frame in a bind, which put the door in a bind, and would make it hard to open.

Don't know if you did. But the stabilizers are not for leveling.
