I've purchased, but not yet installed two 110v mini splits.  One in the bedroom (back) and one over the driver.  My goal is to have the exterior of the bus look stock original (nothing on the roof).  I added a second 300 amp alternator to charge house batteries which should be enough to run the front if not both while on the road.  They draw 9 amps AC or 90 amps DC.  Planning on a 1000 ah house battery pack.

Thanks for all the inputs.

My bus is going over to John Silver at Central Florida Bus.  Plan to look at a couple options that have been suggest.
The first, if we can use part of the old over the road air.  I did remove the motor and compressor, but the lines and condessor in the front may still be in tack.

I like the mini splits.  However, they would require more power.

Thanks,

Bill

Bill;look at drivers aux air on prevost like Ace. Use Ford type techumpsy (sp) ac compressor driven off cam shaft. Mount (facing engine)lower right. Compressor should be under $200 new. Evaporator would go in your defroster box and use those fans. You should check and see if  there was a original evap there someone disconnected . Good luck  should give you 25 to 30,000 btu    Bob      Example 75 ford pickup .

Bob -

Bill's MC-9 came from the factory with dashboard A/C.  Unless somebody removed it, it's integrated into the defroster (evaporator, expansion valve, etc.)  Had to have the main coach HVAC on for it to work, but that can be easily overcome with some wiring changes.

This would be the simplest way to have OTR A/C for the driver, by adding a small automotive compressor, a condenser, and utilizing the existing OEM HVAC plumbing.

FWIW & HTH. . .

Yup, Rigmaster carries on...

For the busnut, I'm not sure that one of the truck type APU's is the best bang for the buck.

You have to add up all that you get for the dollars, and compare to a good diesel generator from someone like Wrico or Powertech, and adding generic HVAC to that.

The truck APU's may meet the needs for the driver's area for air conditioning capacity, but not for the whole coach.

A sleeper cab is a lot smaller inside than our bus conversions.

That being said, do your math, a Rigmaster has lots of generator for powering other AC units besides its own built in one.

happy coaching!

When we install an APU with heat/cool, we drop a drape behind the driver, so it is just for the driver, preventing the need to run the entire coach system.

It can also be used in conjunction with a whole vehicle system, to keep the driver more comfortable. I was not suggesting it would cool the entire, or even a major portion of the, vehicle, but it does save a lot of money, when traveling alone, or with only one person sitting beside the driver.

Add to that, it also powers the fridge, computers, battery chargers, other basic 110/220 stuff, it is a serious consideration for the vehicles we work on.
