My cruise airs draw 11-12 amps which means 24 amps per leg with all 4 running,I usually see 35-40 amps per leg with battery chargers,water heater,water pump,etc. running on each leg total.

That sounds logical to me, Jon.
And, I wouldn't trade my genuine Prevost OTR air conditioning for a roof load of air conditioners.....
I kinda like the way my sun glasses immediately fog up the moment I step outside the bus on a nice hot day
Paul, if you search "tapecoat" you will find a thread about their product. It is an elastomeric and I applied it to my roof about 16 months ago. I think it definitely improves the heat rejection characteristics of the roof. Product still looks great and does not show any adverse weathering or soiling.
On the other hand, the white color is very visible on the roof if you are standing back from the coach. Doesn't bother me, but it may bother some.
My original color was metallic gray or silver, so if you go over your black with the tapecoat product, I suspect you will really notice a difference in temps.

Gordon,
Thanks for the info. I'll definitely check into this product.
My paint scheme is essentially a black outline, probably a foot or so wide, around the perimeter of the roof with a dark gold color center. I wouldn't mind a white roof color at all.
Jerry,
Your post mimics how my systems work in extreme heat. However, I have found that if I lower all my salon window shades, I notice a significant decrease in the heat load from the outside. During a run through Forth Worth with 105 temps, I lowered my shades and the roof airs started cycling.
Such a simple thing as lowering the shades reduces the heat load inside the salon area significantly.
Also, I have installed an insulation product on my roof. I can not remember the name of the product. I am currently on the road, when I get home I will look up the name from one of the leftover cans.
I can't tell if the coating or the lowering of the salon shades enabled the roof airs to cycle during the high heat.

I would think that not only would your shades keep the heat from in, but the cold from going out as fast. Rick
JDUB,
Wally Melia at Freightliner in Houston is using a"Cool Coat" application on our roof after he removes the old clearcoat. On mine, the removal is a 30 hour job because he is removing the sealant around all roof attachments, a/c's etc. The application he is using is the same product recommended for school bus roofs. I do not know if this is a good recommendation or not but trust his judgement and experience with the product. If you want the specific name, I will obtain it for you. It is white and I believe more of a soft finish which I assume is of a rubber type base... good or bad?? Thoughts?
