Wow, I can't believe you got that out the hatch?!  Mine had to remain in the rig while I did all the other work, then I slid it back in place.  If you are re-using your shower, check my thread on an easy way to keep rodents out from the gaps in the floor where the toilet drain goes.

I just wanted to clarify I was wondering what you used to jack the shell up?  Bottle jacks, scissor, floor?  What point did you jack on, how did you keep from cracking the shell? I’m sure going slow is key, but did you do anything special?

Here’s a pic of the shower once I was able to move it out of the corner. You can see the floor has damage under the propane storage box.  You can probably also see the bow in the floor which is particularly bad in that rotten corner.  
To get the shower out I had to tip it to the side and then turn it to remove it.  I couldn’t tip it toward the front or back because there wasn’t enough clearance.  I couldn’t slide it straight out because there is a lip at the rear hatch.
