I see others have talked in the past about rear AC units for a defender 110. There are several solutions with varying degrees of cleanliness for install.
What are the obstacles with using a rear AC from a more common vehicle like a Honda Odyssey (or insert any other rear ac equipped common vehicle) There are a shit ton of these on the road and subsequently alot in the you pull it lots. Also toyota/honda air is pretty fscking cold!
AC rear or front is just a matter of ducting cold air to where you want it ... the issue is the generation of that cold air ... that means compressor, condenser, fans etc. This is going to get very complex very quickly.
The simplest solution may be to install a capture hose in the front system with a fan that pulls / pushes the air to the rear via flat insulated ducts.
This is how NYC taxi's solve the problem.
