I would bet your bike rack would interfere with your jack on the front of your trailer.
If you have a 5 bike rack, (Thinking Thule, cause I have one that holds 5) it takes up a lot of real estate behind your vehicle. I think you'll find it causes problems.
I used to have a popup, and I added rails (tracks) to the roof of the trailer, then used a Thule roof top rack system, it worked great. As you can see, I have two kayaks and two bikes up there in the picture, with the configuration I had, I could carry 5 bikes easily on the roof, or 3 kayaks, or a combination of both...
