They make it a bit harder to remove the heater than they needed to.
The outlet duct sticks through the 'panel' there,
If you've got a panel across there, take that out.
Then remove heater cover, then heater.
If you have a passenger rear seat, not a Z bed or anything, you might have
to take out the lower part of the rear set.
But it does just come out. , just more fiddly than they could have made it.
I mod them a bit so the heater cover comes right off. And the heater comes
right out. 

for the coolant - the best way is to replace the T junctions ( that supplied
rear heater coolant ) under the van , above the trans, with straight-though
hose connectors. Metal ones. 
You don't want those old plastic T junctions in there, even if one leg is
blocked off - they just break. - plastic you know - heat and age. 

Access is medium bothersome, and it's messy. 
Have fun !

Subject: Best place to put batteries and how to remove rear heater core.

I'm going to put 2 Golf cart sized batteries (136 lbs) under the rear seat
and I'm going to remove the rear heater under there. I think it's probably
best there from a weight and handling point of view. Eventually I will have
a different little heater like an espar under the seat but not in the
center.
How to best remove, the entire heater, w/o removing the seat? How best to
reconnect the coolant lines? Thanks.
