We also did our 2nd trip this past weekend. Can't relate to any rear sofa or rear bath problems as we haven't had any. Our leak on the shower was fixed by installing a bead of silicone on the inside & outside of the shower door track rail.
We did have a problem with the front bedroom pocket door. We closed it the second night out & it looked us in.
That is once closed it wouldn't slide back in. Come to find out its the bottom of the door sliding past the bottom u shaped thing ? that keeps it in place. It's like the door is a hair to narrow or that u shaped thing needs to be mounted a little farther out. Just not sure how to get the door off to make the fix.
Also need to move the sewer hose holder. Getting down on your hands & knees to reach that is for a much younger guy than me.
