I haven't had a rear heater for months -- took it out the week I got the 
van, actually.  For a while, I had the hoses looped together under the 
seat, but they were just in the way and at risk of being damaged.

Just this week, I went to the source -- the T-connectors where the hoses 
branch from the main heater hoses.  Took out the T-connectors and put in 
a straight pipe connector in their place.  No plugs, no loops (both of 
which were criticized by others on this list).  Just be careful in 
handling the hoses.  The manifold that the main hoses attach to toward 
the rear is old, and may be brittle.  Also, you'll need (as I need but 
haven't yet) to plug the holes through the firewall so gunk doesn't come 
into the storage compartment under the seat from the roadway or the 
engine compartment.

BTW, so far as plugs and loops, plugging the hoses is no different from 
having the heater valve closed, and looping them is no different from 
having the heater valve open, so far as coolant flow is concerned.
