Finally getting around to installing a Coleman Semi Truck Back Wall Heating A/C unit # 46103-8114

 

http://www.airxcel.com/coleman-mach/products/roughneck-marine/backwall-ac-for-truck-cabs

 

Picture of unit:

Had to move the JOBOX (after unloading Jeep spare parts and tools)

The stack bracing will be relocated too.

Per the instruction diagrams this is how the unit is supposed to mount.

Sleeper interior side and back panels removed.

Unit mounting plate, trail fitting.

After a lot of head scratching and careful measurements the holes were cut thru the back sleeper wall.

Lower stack brace relocated, upper will get the same treatment after unit is hung in place.

Use a couple of boards to determine depth of standoff bolts for mounting the interior duct assembly.

The supplied standoff's were nowhere long enough so I had to fab some up (guess I forgot pics of those).

Now ready for final installation of the mounting plate and unit will be ready to hang.

 

Other plans: some sort of insulation and sound deadener on the sleeper walls, install some side windows.

Nice.....certainly will look better than my 8k window unit sticking out the back of my 780. My unit is cool-only but does a good job. I'm sure you will enjoy your new A\C and heater. Be safe, Charlie

I have been lusting over one of these for years. I will follow the installation with mas interest. Thanks

What are you using to water seal the opening? I am installing a split AC/heat system in the spring and have been wondering how best to water seal.

 

For closed cell foam spray insulation on the sleeper cab ceiling and walls, I plan to go this route as soon as things warm up:

What are you going to run it off of.

Will be able to run it 1 of 3 ways: Inverter, shore power or generator.

What are you using to water seal the opening?

Apply lots of 100% clear silicone between the mounting plate and sleeper wall.

 

There is a thick foam gasket that is peel and stick to the mounting plate and then pressure fits to the unit.

I'm not sure they are even available any longer?

I had watched this one on eBay for about a year.

Price kept dropping each time they relisted it.

Ended up getting it for less than $1000 and the RV place that had it was semi local so I was able to pickup and not pay shipping.

They are still listed on the Airxcel Website. I have seen 1 or 2 recent installations on trucks at shows where I have picked up trailers. I am considering this alternative:

Waiting on some electrical parts to come in.  Need to blow a hole in the floor of the driver side storage compartment for the unit wiring to come thru.

Very close to wrapping this up!

Power to thermostat, check.

Couch in stalled, it covers the vents.  Don't think this will be a big deal as more than likely it will be laid down as a bed if backwall heat/ac unit is in use.

The back wall unit performed great.  Just returned from a 10 Jeep trip.  Slept in the truck and couple nights and ran the unit A/C on shore power.  It will flat freeze you out if need be.  It is a little loud & do wish it had adjustable fan speeds.

And yes I was hauling a full size refrigerator on the truck.  I loaded it with pre-cooked BBQ and fed about a 100 of my Jeep friends one evening.  Plus it's handy to keep several beers cold!

Parked one evening at Moss Field, Webster Groves, MO.  Cousin is the head football coach.

Very "Cool" Chief!  Recently I was looking at a 610 or 630 and I thought I would have to have those side windows.  Nice job!!

I would like to see more on the gen mounting as well. I purchased a 6500 Onan a couple months ago, but haven't decided where I want to mount it. New ideas are good.
