Not asking for much....

With no insulation. You're gonna need a 10 ton, maybe 20 ton unit to do what you want here. Be aware the A/C side pulls some power, but the heating side is where you'll need alot of power to run the unit.

I was being facetious>sorry the tone of my voice doesn't appear when i type.

Amazing how people in general don't comprehend the value of good insualtion for BOTH heating and cooling.

Not only insulation but AIRFLOW. I hauled a trailer for a Microsoft Tour that folded out to a 40X40 stage about 12 ft high. When we started out the A/C wouldn't keep up, I redesigned the airflow and let's just say the first show after I did it, the results were "Peaking".

Those are the max and min temps and those are the extremes. I know it sounds like a lot, but after all of the equipment goes into that space there really isn't much air to cool or warm all all. The space may be 24 feet long but 2/3 of that is filled with equipment so really it is like cooling an eight foot box in the front of the trailer. It is to keep the stuff from freezing and the other stuff from overheating. The power requirment is why I am asking. I know I will need at least a 30KV unit. All the reefers I have looked at will only have 20KV generators on them. I am not saying that insulation is out of the question but it won't be a reefer trailer. That style of trailer just won't do the job. If it was easy to find something to do the job I wouldn't have asked here.
