P-trap for shower

[Emdixon1]

I want to know if anyone can give me direction on how to get access to the p-trap for the shower on a 36fl 2013 redwood before I start plowing into it. Do I have to remove the shower or go underneath to get access to the top of the gray water tank?
I would appreciate some insight on this.

Sorry, I can't help, but I have a 2014 FL36 and I dread the day my shower drain starts to leak.
The only insight I might have is that shortly after I received my unit, one of the sewer handles, in the small compartment on the outside of the trailer, actually came off the wire that opens/closes valve. The only solution was to remove that cover which has some limited access to the shower. To be honest I can't be sure this would help.
Once I had this compartment open I was able to crimp the handle back onto the wire. Every time I open that drain valve I keep thinking "will it fall off again".
