I am relocating my rear ac in my 70 burb to under the second row seat and building a custom console to duct the air...but I am going very slow on that build so can't say how it will work yet.

On the aux heater issue the later suburbans had an aux heater in the back from the factory, real small with a core & fan that you could transplant into any other rig.
