down at least 3" in some places. We don't have a hoist so we are thinking if using jacks on both sides starting at the wheel wells and working forward and then backward for each 4' section. Exterior walls are fiberglass. We have to remove the lag brackets to lift the camper shell up.I can't find any video or pictures as to how to lift the shell. The windows should have to come out as not to put them in a bind and brake the frame. Any suggestions are welcomed. We have two weeks to get this done and put back together. This is our home and a new job starts in January.
