RE: Shore works ATS in and out on Gen power
Who would have ever thought a belt tensioner could cause this issue ?
Does this mean the engine drives the gen by a belt ?
Have you run it long enough to be sure it is actually repaired ?
Or maybe something was disturbed causing it to work for awhile .

RE: Rooftop AC Tripping Breaker... Sometimes
Thanks for the feedback everyone.
I'm sure the coils are as clean as they can be. They weren't too bad to start with, but I used a shop vac with a brush attachment to get the few items that were large enough to see. I then soaked them with a foaming coil cleaner and finished them off with a good rinse with the water hose. I did this with both sets of coils.
I don't think it is the supplied voltage either. I have had the same issue at 2 different RV parks, using the generator, and plugged up at my home.
I'll check the amp draw using an extension cord. That should tell me something. I don't think the coach has the amp draw on the EMS, but I know where I can borrow a meter.
With the additional info you are more than likely looking at
replacing the A/C . You know its drawing excessive amps
because the new breaker trips .
You have already gotten more yrs of use than most .
Be sure the new unit will communicate with the thermostat
and the other A/C or go ahead and replace both units and
thermostat .
That's what I did , 2 new A/Cs and thermostat .
I didn't really want to spend the money but DW said I ain't
going if its hot in there . Glad I did now .

RE: Rooftop AC Tripping Breaker... Sometimes
I fear ultimately Doug is going to be correct , bad compressor .
Before condemning it though I would give the condenser coils
on the roof a through cleaning again . Stuff can get imbedded and some
areas are hard to get at .
Also some A/Cs have a foam rubber strip under the plastic cover
that helps keep the air flowing through the coils , it needs to be
in place or some air can bypass the coils .
Do you know what the park voltage is ? Low voltage can cause problems .
This time of the year everyone is running their A/Cs full blast which
causes low voltage through out the park or probably the entire area .

RE: roof air
Doug, your response to this gentleman was very rude. He simply stated he had never seen this type of installation, as I have not either. We are all on this site for learning not for unwarranted sarcasm.
Well I'm not the first or only.
I don't care to be offended that easily more important things
in my life .
Btw I don't remember stating I am a layman

RE: roof air
When you state you have never seen that design. WHAT is your qualification to state that? THAT design has been on Newmar's for over 25 years. Airstream uses a similar mount. Tiffin has used that type mount for almost 15 years. Jayco uses that type mount(top down) used that type on some of their models. ANY RV unit that has NO 14 inch square inside duct cover access will have top mounted system. That pic is on top the roof. Doug
WHAT is my qualification ?
Well how simply can I say it ?
All of my RVs so far have been the kind that bolt from
below and I haven't gone around asking other people
how does you air cond bolt to your roof .

RE: Air Conditioner Performance
We have run our gen day and night for as long as we needed it .
That's what its for . I'm not going to try to sleep when its
hot while all I have to do is start the gen .
Diesel is currently cheap so spend some dollars and sleep well .
Actually the Onan likes to run .
Low hours on one is not always a good thing .

RE: Air Conditioner Performance
I keep a couple of small fans in the RV . I us them inside and out
Sometime I need to blow the cool bedroom air up front
While I don't think you will put to large of an A/C in your RV this
reminded me of a man I worked with yrs ago .
He had an A/C in his home that was way to large for the home .
It would get really cold but they were still uncomfortable .
Finally an air cond man explained to them that the unit should be
properly matched to the area and heat load otherwise it will not
run long enough to remove the nasty Texas humidity .
That was it they were cold but clammy feeling .
On the other hand if the unit is to small you may never get cool .

RE: roof air
Yours is going to take a very specific replacement, depending on what you have. It is lag screwed in, instead of bolts. Here is a picture from one of the training power points showing a Newmar install.
http://bryantrv.com/images/temp/rvnet/newmarinstall.jpg width=450
NOTICE that gasket that goes between the 2 roof holes. THAT gasket is critical for correct operation. It separates the Intake hot air from the cold exhaust air and if not installed or installed incorrectly, you will not get adequate cold air output. The Lag bolts are installed into a wood/aluminum backer plate. Just make sure you measure and drill the 4 holes in the New AC mount pan, exactly where the original ones were, Do NOT over tighten the lag bolts or you can strip them out of the Aluminum plate. Doug
Something new to me , never seen that design .
Those lag bolts , are they from the roof or from inside the coach .
Drilling holes in the new a/c pan sounds like from roof
Couldn't tell for sure from the picture .

RE: Help finding nightly parking for our caravan
Another advantage of Town / County fairgrounds is you will more than likely
find a lot more open space and they are used to animals , animals is what
fairs do . We stayed at the Louisville Ky fair ground which was an asphalt
parking lot but plenty off space , acres & acres
Not cheap though , 50 bucks .
Truckers are working trying to make a living . I don't see them looking
kindly at a dog caravan taking their parking places .
We have stayed at a Cracker Barrel but with your 4 vehicles they might
frown on the idea .

RE: Help finding nightly parking for our caravan
Town / County fair grounds , many of them even have RV spaces .
They might be mostly empty in Nov .
I would start calling now .
We stayed in one in Oct in Kentucky that was empty .
I mean no one at all , we left the fee in a door drop
at the office .
It was a little spooky just the wife and me but there
will be several people with you so being alone would
be better for you .

RE: roof air
choppermtn , you should give some info so someone can know what you
are working on . Tell us what brand of coach , year , make of a/c etc
You may even find a picture on line we could look at
What you described does not sound like most coaches or at least like
anything I have seen .

RE: King Dome
We like the in motion satellite so when ours stopped working I caught
a sale at Camping World where I bought a Weingard T4 for $900 and installed
it my self . It works great .
I know Direct Tv may change things but I decided to do it anyway .
Now it seems Direct TV may not change things that much after all , we'll
see .

RE: Evans Dash Air Nightmare
Not sure what you mean by vacuum motor but there is no motor in the
black box . You are exactly correct , 12v operates an air valve ,
air is the passed thru the venturi to create vacuum as needed .
When done right the venturi is a terrific little devise but I suppose
the 12v pumps became so cheap and good where the black box probably
got more expensive so the bean counters won again .

RE: Evans Dash Air Nightmare
Well lets update your Understanding.
1. RV Motorhome makes do NOT utilize Dash Air from the Auto Industry(including Monaco). They are supplied by companies that specialize in aftermarket Dash Air systems for the Motorhome market. Been this way for over 40 years. The only exception was the original 1979 thru about 1985 Silver sided Chevy Chassis Airstream motorhomes Class A
2. ALL DIESEL Dash AC systems use a 12 volt vacumm pump to supply the needed power to move the Air Damper doors when the Motorhome has a Vacumm activated system.
3. Most modern Diesels/Gas in the past 10 years or less use a Electric motor activated Damper door system Like a Denso system. I believe all Evans/tempcon use Vacumm systems. So, If you have Evans/tempcon you have a Vacumm system. Doug
Ok maybe not , guess I could have worded it better but some
components are plain old auto parts store stuff available most places
I can't say for sure but have been told my dash air control ( knobs etc ) are Ford .
As far as the vacuum pumps you are not correct when stating that they
are all elect . Monaco used an air through a venturi vacuum gen at
one time
Google will explain how it works . I located a picture of one on
a 2000 Windsor but couldn't post on here .
Maybe this link will work if anyone wants to see one .

RE: Evans Dash Air Nightmare
I have a 2001 HR Ambassador. The Evans Tempcon P/N on the molded plastic evaporator housing is the same as referenced, and also has cracks. I was able to find a couple of PDFs of a service and trading manual (the web link doesn’t have much other than a knowledge base with little knowledge). The Newmar training pdf has a schematic of a typical pusher install wth a vacuum pump and reservoir (troubleshooting guide points to this), but my install has a box with the 12= supply, the vacuum line to the reservoir and a red polyethylene line going to the back. Is there an option to get vacuum from the diesel? I didn’t think that worked with a turbocharged diesel. Anybody know?
Here is the way I understand our air cond .
Monaco used dash air from the autos industry .
These air conditioners used vacuum to control system .
You are right that diesels don't generate vacuum like gasoline
engines so we have to generate our own vacuum
They did this by 2 different ways , one is a box looking device
that has a ventura inside where air is passed through to generate
vacuum . More recently they use a 12volt vacuum pump , borrowed from
auto industry , Ford I think .
Mine is mounted above the generator on the firewall .

RE: Miles per day.
I'm 86 years old , only been at it since 2001 .
Recently switched from diesel to gas
Congratulations on being able to still RV , tell us your secret .
I'm 78 so maybe I can RV another 10 yrs , I hope so .
Many people at 86 can't get into a Coach and sure couldn't drive
one .
However people are living longer more active lives so there may be
more seasoned drivers out there than I thought .

RE: Miles per day.
I to have done the marathon drive of 1000+ miles at a time. Now I think 500 would be about the limit as most trips the last few years have been in the 3-400 mile range. 78 years old so I guess I am supposed to slow down some, maybe.
Interesting that our driving experiences are mirrors and
really funny our age is the same ( 78 ) .
Hey its better than the alternative .
Yes I have slowed down too . In many ways I enjoy slowing down .

RE: Miles per day.
We used to drive a 1000 mi to get home at midnight Sunday to go to
work Monday . That was crazy but we managed .
No more of that I'm way to old now but still usually drive 300 to 400.
Here in Tx 3 to 4 doesn't get you very far from home

RE: Can I use a WDH on a DP
The simple cheap answer is to get 2 or 3 bags of sand .
Put them in the in the rear of the trailer .
I don't think a WDH will confuse our air ride height at all
After the WDH has distriduted some weight mostly to the trailer
the air ride will adjust as necessaary .
My ride height system takes over after I start the engine .
How will it matter if the coach is already level ?
Now if you decide to dump the air or level the coach when you
park that may put a lot of stress on things .
