I can fill up all 4 of my 35s from 11 to 30 psi in about 8 minutes with the ARB twin. It is a sizable investment for just filling up tires though. I use mine to push a locker (2 in the future) too.
Damn, don't know how I missed the video of your cruise in this thing, it looks like a blast. Progress is looking good. Rigs like this put a smile on my face.
