Richard, the HS2800 will in fact fit , it just takes a bit more trimming
on the side of the seat box where the fitting needs to go, and a tight
turn on the flex ducting to the heat outlet. I've done at least one that
way. You can also run the ducting through the top of the rear heater
cover and to an outlet on the other side. That's how I had mine
installed years ago, leaving the existing heater in place.

I have a new Propex 2800 for sale. I bought it ~5 years ago; the first
group of 2800s that Karl brought in. But I have a Carver installed and
so never got around to it until last spring. I determined that the VW
underseat heater needs to be removed for the 2800 to fit; I didn't want
to do that. (Westy talk)
