Where is the external shower located on a 16, or 17 for that matter. I have one to install on mine, but I have heard they have changed the location of it recently.
I thought I saw a thread that described them being installed on the rear of the van due to some rule in relation to the potential of water being sprayed into the electrical inlet.
I think that was my thread you saw Brad - but I have the 14 foot with blank rear wall. The shower has been installed on the rear wall near the number plate. i expect in the 16 foot it is as far back on the offside as possible.
