Swap heater for a/c?

My 2006 Ford E350 SMB has a Suburban propane furnace in a RB50 build. I will not need the heater where I am going, but will need a rear a/c. Asked SMB Texas about the conversion and they quoted +$6000 and 10-12 weeks. Ouch. Looks like Danhard is my only option (not interested in an exterior unit). I am pretty handy. Anyone have experience or advice on a DIY heater removal and a/c install?

Just thinking out loud -
Possibilities of installing an efficient 120v powered unit and running it off the inverter?
Roof Top A/C except shrouds are pretty big?
A/C unit out of an All electric car?

A few people of installed bedroom window units in the rear door window locations.

Running an adequately sized AC off an inverter will be quite the challenge, but a soft start will certainly help. Roof top units work well but are heavy and require a generator. This question comes up every summer so a quick search of the threads may find a good solution, please post your solution.

I have an IndelB fridge (from Truckfridge) and have been pleased with it. Have you seen their website with 12v/24v air conditioner products?

Danhard makes a self-contained marine A/C rated for 6,000 BTU, that might fit your furnace compartment. It draws 5.7amps at 120 volts, so a modest pure-sine inverter would power it (modified sine will increase the current draw, and make it run hot and could shorten its life).

https://www.marinaire.com/Marine-air...BoC9xwQAvD_BwE

6,000 BTU won't cool an already hot van, but it should keep it cool if you use the dash A/C for initial cool-down.

Check out Dometic Under Bench unit.


You would also need the installation vent kit
