I finished installation of the Espar D2 unit and the passenger seat swivel and still need to finish work below the floor. I selected the installation described in the Sprinter/Crafter manual but reversed the flow, the outlet is in the front left seat corner of the seat box. With the seat mounted I still have access to the fuse and the diagnostic terminal.

Ah,
that floor! Now I see what you were asking. My reasons for the wall mount were:
* considered the air flow better when mounted on the wall/angle-mount bracket
* there didn't seem to be enough space on the floor
* the floor was angled which seemed like a complication.
* didn't want the output vent in the space between the seats.
I do like the easy access you have to the fuse/diagnostic terminal ... Crossing my fingers that I don't need this.
Nice install and nice documentation too.
