Excuse my guys, but how do you power all 5 of them at once? Arent we talking a lot of load here, much less start up current? If you run them all at once, do you have any power left for anything else to operate?
Just asking???

I have two 7 KW gen sets, and the book says keep them loaded. I live in Palm Springs, stay in the bus 4 days a week in Norco and teach in Huntington Beach. I do the vinyl part time out of the bus, race cars, banners, graphics and will be off for 3 months at the end of the month. If anyone needs vinyl, summer is a good time. |

I have had two for 20 years and never needed more. The only thing you need to watch is that the front one is as far forward as you can possibly get it. As you won't have cab air you need to close off the rear vents on the front air to force as much air out the front of it on a real hot trip. I even have small fans in the top corner on each side of the windshield to blow the cool air onto me when driving. It has worked for me even in 100 degrees in SC. |

Three is better. I started with two 15,000 btu units, one at each end of the 40' bus, then added another unit in the middle. When I am driving I run the front two, when I am parked I run either two or all three depending on whether I have 50 or 30 amp service. Each one is on a separate wall thermostat so they only come on when needed.

I have three and two would probally work just fine. I have used all three at once just to cool the bus down fast.I have two ducted together and the third runs the back so I have a little more control of which part of the bus I need to cool down. Just my way of doing things but it works great for me. |

This is probably a dumb question, but..
Won't all those holes in the roof weaken the strength of
the bus, since the roof is an integral part of it's structure?
Has anyone found a way to run the coach air system on
110 volts when the coach isn't running? The coach air is
too good to just abandon, isn't there a way to make use
of the system? |

When you are in the converting stage you reinforce the roof area around the opening to support the extra weight of the A/C unit. I even did the reinforcing around all openings just to keep the strength in the roof.
It wouldn't be practible to hook up an electrical motor the size you would need to run the coach air. If I remember right the coach air is about 10 tons. I don't think you would make many friends running your engine all day just to run the A/C. Bill |

Sometimes you will need three. Most of the factory conversions that use roof airs that I have seen use three. Even if two will keep it cool you may need three to cool it down initially. I think five is for distribution and perhaps for more bodies in the bus. The engine heat makes the bedroom warm in mine for an hour after we stop, so you will have times that you need the extra capacity. |

Hi Bob,
When you ask how many roof airs you need it would be helpful to know what bus you have, its length and how you plan to use your bus. I clicked on your name to check your profile to determine what bus you have and from that determine its length but there is only an e-mail address there. The above posts suggest from 2-5 airs without knowing enough information. If you post the information on your bus and how it will be used you will get better answers.
Thanks, Sam Sperbeck

The RTSII is built in 5 foot modules and the roof is reinforced with stainless steel supports in each section. The hole is already there in each section for an escape hatch, but they only cut out the roof where the customer wants the hatch(s). No reinforcement needed on the RTS, cut out the hole, build support for the 14x14 inch hole and place the air.
My RV had one (1) 12000 btu air con and it gets plenty cold.
The RTS has Two (2) 15000 btu air cons, one front, one rear. So far no problems.
Thanks for the tip of an extra fan(s) up front, thats a good idea that I will incorportate. Adding these plus the original fan should be helpful.
THERE WAS AN ARTICLE, about someone had an opening, he used the Bright Head Light position, that vented air in as the bus cruised. Was piped in to vents, and controled with shop vacuum slide valves on a wire (choke like) control. Said he had more air than he knew what to do with. Seems when the bus is pushing all that air, it has to go somewhere and it builds a slight pressure and feeds into the air inlet with no need of a fan to back it up. Depending on the space between your headlight and the trim, if you attached a small ventline behind the bulb in the light housing, you would still get air pressure to flood the area w/o loss of the actual headlight. That is theory but when you compute the area of open space for air flow, it seems to be adequate. Besides, if you do not like it, the headlight housing is easily closed off again.
hmm, just thinking

Nobody with six? Interesting discussion, I had two 15k units on my 4905 40 ft, and sure never had any desire for more. I never used both except to rapid cool when the bus was sitting closed up in the sun, and then for only a short time. I always thought that the third one would be nice for redundancy, but not really worth the effort. Putting the front one far forward was a wise move, you could really make it blow down the back of your neck. |

I plan to run two (and wire for three), but I'll be using 9800BTU 12V units. |

Sam, I have updated my profile. It took me a while to figure it out. I plan to use my bus as a motorhome. Probably not full time, though that could change... all the best friends and thanks for the responses! Bob |

We plan on mounting three, (3) but normally only running two; either the front two or the rear two.
This SHOULD allow for more cold air in the front going down the road and more cold air in the...
...middle and rear when parked somewhere. It may also tend to balance the gen set. Good luck. |
