I figure with a roof mount unit like that, it should be no problem to run the AC while pulling hard, since the condenser is not in front of the radiator.

My idea for the truck is:
79 Ford F series cab and front clip. (front clip modded to tilt)
Isuzu Medium duty frame (24 feet)
Dana 80 rear
3 speed brownie
5 speed trans (NV4500)
6V-53T Detroit under the hood
48" sleeper
Nice flatbed

Tiremann,

Yes they do. They are (to the best of my knowledge) round, and about 6 inches across. Generally mounted on top of or behind the sleeper or cab towards the top.
You're right they are round more like a foot across and usually white. The AC unit you posted the link to also mounts on the rear wall of the sleeper, not on top. The roof mounted ones are most likely 110 units like an RV and have an on board generator to power them wich also comes in handy for a TV, microwave, etc.

I just looked at it again...you are right, this one does mount on the back of the cab. The ones I have been seeing are similar to the one in a pic was posted of earlier in the thread. They are NOT 110 RV units. If you go thru an old truck or equipment bone yard, there should be at least 1 of these on an old piece of iron in there somewhere. I have run equipment and trucks that have them mounted...2 of them even worked...most did not. (probably low freon charge...but I never checked into it, since it was not my equipment.)

they are passing a law in CA to get rid of the APU's all together and making the trucks cool the sleeper off of battery power.

Sounds like a hell of a setup if you ask me.

Leave it to California! I can barely speak.......the urge to cuss is that strong!

With all the electronics that new trucks have onboard (before you add all the electonics that the driver adds) The LAST thing that trucks can handle is cooling the sleeper to a comfy temp in 90+ degree heat from the bloody batteries!

Someone down there needs a bit o' this !!!

Thanks Tiremann, I put a lot of thought into the details on it. Of course, I was thinking about adding an APU...still am really, since the engine is already illegal in the Peoples Republic of Kalifornia.

Don't bloody like that state. Actually, the STATE is fine...if you get rid of about 97% of the population it would be great!!!

Finally got passed by a van that had one of these today at a slow enough speed I could write down the name on the unit! (Who sez rush hour traffic has NO uses! ) While I was looking for information on them, I found reference to another unit. Check these out.

Zanotti
Carrier transicold Europe

The second unit is talking about a split unit...but it is a varient on their non-split one if I am reading it right.

Pretty damn cool IMO. Which way are you leaning? I like that Carrier one myself.

I would probably lean that way too...but my current thought is to find out if I can get either one of them here! Since both seem to be for the european market. I will find a carrier dealer and ask about it. (probably easier than finding the italian company! )
