AC Adequacy
Our first trailer had an air conditioner that hung from the ceiling and blew cold air from its vents. It cooled our 18' footer thoroughly and quickly, probably a 13.5 btu. Actually, it could freeze you out in the upper 80s and did fine at temps over a 100. The new unit we've ordered has a 15k and air is distributed through ceiling vents. I'm sure many of you have this system, and we're wondering if we're going to be satisfied with a single unit in this 32 footer. There's still time to add a second, I think.

Just got a 29' Foot and never had a/C in a RV before...

Have the 322FKS, single ducted AC and have not had a problem with cooling in 3 seasons.

Our tt has experienced 110 degree weather with it's 15k btu a/c. It kept the tt very comfortable even in the front bedroom.

If my single a/c doesn't seem to be keeping up with the 100 + degree summer Texas heat, I just turn on a small electric box fan to circulate the air....I have never had regrets for not getting a dual system.

I added surflo (fantastic fan clones) fans to all the roof vents and never use the A/C... turn it on once a year to exercise it....

My 15k unit with ducted air worked just fine last Summer in 100+ heat and high humidity. I on the other hand did not handle it as well as I like to be outside most of the time, not stuck in the trailer by the A/C. I also have a voltmeter plugged into a recept to monitor the voltage. You would be surprised how low the voltage can drop in some CG`s during peak usage such as real hot days.

Every unit we send out of here has a voltmeter. The new models have tons of electric everything and most of the CG's aren't equipped for the drain. We tell our customers to watch the meter and start cutting back when it dipps close to the red. We replaced several A/C Units this past summer due to low voltage strain on the compressors. That aint cheap, and isn't covered under warranty.

Exactly. Low voltage can be a silent killer. Or it can be really low. A buddy of mine went camping during a heat wave last summer, arrived, plugged in and turned on AC and breaker tripped. Looked at his meter, less the 100 volts! He moved to another loop where there was adequate voltage. I had to buy my meter, sounds like you guys have a great dealership there, thinking of details like supplying a voltmeter to the uninformed buying public. I wish you were close by.

Great info! Besides the "red", what is the magic number to watch for? I'm pretty sure Don has a voltmeter, but is the one you supply to customers actually permanently attached somewhere and where? Thanks Wes

Here`s the one I bought: http://automaticstandbygenerator.co....-meter-lvm450/
I believe you like to stay in the 110 to 125 volts range, or green area on the meter.

Green zone goes from 113-127 V. It just plugs into an outlet (we ususally put it in a kitchen outlet and tell them to leave it there.

Because of the minimal amount of outlets in our tt, we use the multi-plug thingy. Does this affect the meter?

Great information for sure. I'll be looking for CCI's answer to Healthi. Jayco says TTs don't get a 2nd unit anyway, but advised adjusting vents if necessary. Not to hijack my own thread but won't my SurgeGuard protect us?

For the few times that I am in a campground I have one of these
http://www.campingworld.com/shopping...rge-guard/2279
I just finished hardwiring it into my trailer... if the voltage is to hi or low or the polarity is reversed it will not let power through...It takes 2 min to check the power line when you plug it in before it lets any power through and cuts off quick if it detects a problem... it saved my old rig twice... I know they are expensive but so is my TV, computer, internet dish, etc etc etc..

I have one of these. They are not cheap but well worth it in my opinion. The unit will boost a low voltage to a safe range as well as providing high voltage and surge protection.

No, the multi plug shouldn't affect it at all. I tell people the $15.00 investment can save them hundreds of dollars in the long run. Especially when they come in because of compressor problems or blown microwaves and they find out low or high voltage isn't covered under warranty.
I also see on here different ways other people protect themselves and I gotta say, they are all great ways of doing it!

Surge guards are great for power spikes. Constant low voltage is what we are talking about with the meters. There are several state parks here locally that had to post notices at the gate telling patrons to use their water heaters on propane only due to the voltage drains they were experienceing. This happened numerous times this past season.

I was referring to the brand, SurgeGuard shown at the link below. So I don't screw up, is this sufficient? It's what I had on my Cherokee.
