Something to consider concerning the tongue jack / stabilizer you've mounted. I used basically the same thing on my teardrop that I built. I thought it was good and secure. However, once you crawl in it it's surprising how much play there really is. The thing moves a bunch when you roll over. You'll have the same problem with your RTT mounted.
If I did it all over again, I would consider something like these as they would remove any play from the trailer. They can be found cheaper but this was the first that came up when I googled it. They mount underneath without really taking up any clearance and deploy easily without having the knee banger issue.
On the other hand, leaving the trailer hooked to the vehicle pretty much removes all movement when you sleep in it anyway. Generally, I just quickly hook back up if the trailer was disconnected and go to bed.
