Anyone know if the 382MBQ is prewired for third AC?

Shoot with two in our 384 I feel like I'm in a meat locker now, we have been in over 100 degree weather an it might take hour to cool down were it's livable but once cooled down it keeps it that way, of course they run all the time  Not sure even if you had three running if a 50amp circuit could even handle such if the DW turned on her hair dryer or fired up the Microwave or convention oven, TV, etc ...

My front living room gets hot during day on high 90’s low 100. Think next one will not be a front living. Our bedroom is cold and when you step down in the kitchen it’s at least 5 degrees cooler. Thinking of putting in insulation in front behind cap .

Thinking of putting in insulation in front behind cap . A quick and inexpensive may be to divert air from your bedroom to other parts of the coach by closing off some vents in the bedroom area. Adding more insulation to the front cap area probably is not possible. The front cap area is already insulated and adding more may compound the problem. See my post on the other thread under general questions about adding a 3rd a.c. Unit. That also is not a viable option. |

Anyone know if the 382MBQ is prewired for third AC? No they are not. You would need more than a 50 amp service to run all 3 at the same time. Mass produced RV with 3 ac units and 50 amp service can only run 2 at a time. |

There has been a number of us that bought vents that you can close off in the floor, but this dozen't redirect cool air since this air flow is in the ceiling as stated you might try closing off some of the ceiling vents so the cooler air is re-directed to other parts of the unitas stated before ... Also redirecting the air flow by turning the vents in different directions may also help, opening the bedroom door during the day may also help to cool it down, closing the daylight shades also help or even the nighttime shades help to keep the heat out .., We often roll out the awnings if are trailer is in the westerly direction to keep the inside of the unit cooler ... Hope this helps Chuck |

As Chuck mentioned, getting the “closeable” floor vents (so you don’t lose cool air down them) is a good step. The same is true for blocking off the furnace return air vent for the same reason ... those two easy things will keep your cold air in your living area and not lose it to your basement. Something else that helped us was to open the “quick cool” slats on the AC units. That alone seems to double the cold air output of each unit.
For reference, last year, with none of these things done ... temps in the 100’s the best we could cool was 89 interior temps, which was miserable. So a delta of 11 degrees. After doing the things I described, we are in Liberal, Kansas today with outside temperatures at 103. We have no shade and are sitting in a gravel spot. Our current interior temp is 78 ... a 25 degree delta ... which is fantastic. Amazing how a few simple changes, and learning how our equipment works (I thought that if you opened the quick cool slats all the air would come from them and not the ceiling outlet vents). Fact is that just as much air is coming out of the ceiling vents as before, but in addition to that we have a great amount of cold air coming out of the quick cool slats. It literally feels like we doubled the cooling provided by each unit. Hard to argue with the results we’re getting.

Cheap option. My DG was not pre wired nor was the rear Bunkhouse boxes in for a third AC. I had my dealer frame the AC and install it while it was down for warranty service. They took pity on my after having it the better part of a year and installed it below cost.
I bought a heavy duty extension cord (10 gauge) and wired it up to the AC. The cord is attached to the ladder and another 10 gauge extension cord will be plugged in at the camp site to run the third ac if needed. I have read about several people doing this and no one had any issues as long as a heavy duty cord was used.

I have read about several people doing this and no one had any issues as long as a heavy duty cord was used. I've seen any number of people do this with 30a trailers so they can add a 2nd A/C. Some go fancy and add a breaker to the panel, and a 2nd external plug, so it's neater. Others simply have a plug at the 2nd A/C and run the cord off the roof to the pedestal. Another =real= easy solution is called a FAN. Simply blow the cool air from the lower area into the upper area and crack the top vent to get a bit of convection going.  Lyle |

Lyle I installed the plug on my last trailer (30 amp, Crossroads) and had to rewire the breaker box twice. The installer didn’t wire correctly. I decided not to cut a hole in the wall of my 5th wheel to install the same marine grade 110 plug. |

Mass produced RV with 3 ac units and 50 amp service can only run 2 at a time. At the recent RV show I attended, I talked with Charles (the regional rep for this area) and the subject of a third AC came up. He told me they can now do that and KZ wires the third AC with wiring that is sized to allow all three to be used simultaneously ... not like many manufacturers who do not use more expensive wiring and must “load manage” the three units so that only two operate at a time. The power required isn’t a problem because “50 amp service” is 50 amps per leg making 100 amps total actually available. |

There is one more solution to adding a third air conditioner. In my unit, the 3rd ac installation can be in the hole currently occupied by the max air exhaust fan in the kitchen. It is a 15kw unit (could be a heat pump) it is not ducted but just an old school blows out of the inside unit. It is powered by a separate 120v 15 amp line that plugs into the power pole ... this allows all 3 to run simultaneously and will cool the house down no matter what the temperatures. It also serves to provide a way to still cool the rig if one of the ac’s goes down. It is an intriguing idea that I am seriously considering. Just something else to consider.
Update. I've got the third AC on order (backordered really), and hope to have it up and running late August. I'll let you all know how this goes.
Third AC installed today (12 Oct). 15,000 btu with an electric heat strip. It’s still hot here (99 yesterday) ... looks good, looks like it has always been there. The tech did a good job of routing the wires for power and thermostats so that they are out of sight Very professional installation, power is in the wet bay compartment so that the power wire goes out the same hole that the water lines go out. No new holes (or possible water leaks) in the side of the rig. We’re ready for just about any temps now. Some might consider this expensive, but a very good upgrade, and this is our home, so worth it IMO.

Thinking of putting in insulation in front behind cap . I'm working on the right now, living areas good, bedroom no so much. Wish there was a vent & fan in there, might be another add here in the future. |

Good to hear they are going with third ac option. I have been here pleased with the way my two units have handled the 105-110 west Texas heat. On a side note after first of year we are probably gonna put a home on land we just bought, and sell the Durango.

On a side note after first of year we are probably gonna put a home on land we just bought, and sell the Durango. For us, the highest temps we’ve hit is 107 and by pre cooling the rig early in the day, we have been able to keep the rig comfortable (80 inside). Honestly, I think that’s about all this rig can handle. This is what brought up the third AC discussion. Although it doesn’t happen often, we have seen 115. That would probably put us in a hotel. |

My bedroom which is in rear of trailer is always much colder than front. Which I’m sure is because it’s 1/3 of the space and high ceiling. When I close those vents it helps front a lot, but yes those temps are about limit in direct sun.
