One thing that surprised me on this rig is that they did not remove the rear stabilizers after or corresponding with the HWH install. I don't know yet if they're still operational but will find out soon enough.
I removed ours to save the much needed weight. It's about a 10 minute job.
Disconnect plug and zip tie to hitch
Place floor jack under stabilizer to hold up (Learned from AZ Expert)
Remove 4 bolts
Lower floor jack
Done
