I ended up getting an SKB 4 space rolling rack (retractable luggage handle with wheels) to hold my XL II + as well as an RAC12, Furman PL-8 (for power conditioning and cord cleanliness) then I had a
Best-Tronics make me a custom patch panel which was icing on cake.
The patch panel has Powercon locking power connections (for my XiTone wedges and the Furman), audio connections (XLR and 1/4" for output 1, 1/4" for output 2), USB connections (Axe FX and RAC12) and finally and XLR connection for the the MFC101. Now I don't have to dig in the back of the rack to connect anything. To be clear, the SKB rack has rails on the front and rear so the patch panels is mounted on rear rails.
Last but not least I bought a blank 3 space rack panel with I attached with big thumbscrews so I can open it up without a screwdriver.
I consider everything in the rack essential and as compact as it can be.
