The Engel units are really sweet..  Got to witness this first
hand, @ this years SdM.  Lucas and Taylor both have
them mounted in the passenger 'jump' seat position in
their Syncro Westy Weekenders.  Wired to a Solar panel
on the roof via deep cycle battery, it's a nice setup, with
freezer section and all!

In a weekender it works great, in a full on Westy, this
sort of arrangement takes up way too much space.

Here's what I'd do if I had the resources/time.

Remove rear heater core.. plumb in a nice propex unit
under the rear seat.

Remove the Dometic Fridge, and relocate the water
tank to that cabinet space.

Remove the shore power outlet, and modify that
rear beside seat cabinet and drop in an Engel there
(venting to the outside if possible)

If you wanted to forgo the storage space, you could
make it one huge 'drop in' frigde/freezer space.

The Airstream Sprinter Westy's have something like this in
them.

I've already got a nice atwood propane RV furnace in that
spot (where the useless smal cabinet/shore power outlet
is/was?)  or I might seriously consider such an option.

Of course, I'd be ruining the value of my van, since we all
know it's only worth $6K since now it wouldnt be 'stock'! ;-)
