Fan question

No debate intended here between the max air or the fantastic fan. Iím wondering if they accomplish what Iím looking for. On a warm day my trailer tends to be about 4 degrees or so warmer inside than out. My TT didnít come with an exhaust fan per se, other than the cheesy fan in the bath that does work to remove the shower humidity and thatís about it. Iím thinking of having one of the two brands installed hoping it would equalize the outside and inside temperature. Is my expectations realistic? My neighbor has a fantastic fan in his fifth wheel and he says it doesnít do anything. I doubt that since Iíve seen many rave about theirs. Iím hoping to reduce my need for AC. I have an exhaust fan in my home that works wonders. Since there is power in my bath Iíll probably put it there. Thereís a ceiling vent in the bedroom as well but I think the bath is more practical. Your thoughts?

I have a Maxx Aire in my living room and one in the bathroom. We'll open the windows and turn the fan on blowing out and it will cool the rig nicely. Can be difficult to cool down in the bright sun depending on how well you're insulated.

Yes, no, kinda, maybe. It is all about creating air flow.

In an older trailer I had with no air, but 2 vents had 2 Fantastics. I would set one to "in" and one to "out". It moved a fair amount of air, but hot was still hot......

In my current RV I only have one vent (in kitchen) that can have a fan in it. It does have a Fantastic also. If open many/all of the windows and doors the fan does not help. If I open the bedroom window, and put a fan there to help draw in air, and turn the Fantastic to "out" it will create air flow which helps and can be felt. Again hot is hot.

I find this works best for us in the evening when it starts cooling down outside.

Again it is about creating air flow.

Thank you. Iím not confident to tackle the job myself so will pay the dealer when I get back home. I need to take it in for a wheel repack anyways. My goal is if itís 75 outside Iíd like it to be 75 inside not 82. That goal may not be realistic but Iíd
Ike to be close. I find when the sun goes down and I turn the air off itís about 74 outside but the inside temp climbs up to 80 or so after I shut the air off. My bet is the trailer is heated up on the outside from the days son. Hopefully the fan will battle that. I hate running AC and I only use it at home if itís absolutely miserable.

pj48009, My wife hated AC just like you do, but I've finally convinced her to start the AC before she gets hot and run it longer after the outside cools down. There is a lot of heat sink in the walls and roof of your RV. It takes time to cool it all down after a hot day and a fan won't do it. As far as fans go, if only one, set it to exhaust and open a single window a bit to get the airflow you want. If your RV will take it install a ceiling fan where you have a 120v light. You need 12v at the vent where you want the ceiling fan. The bath has 12v for sure, if your other vent is not prewired, it could be between expensive and impossible to get 12v to it.

I guess the question at the end of the day is will it be worth it to spend about 400 dollars to install one? I’m guessing at the price right now between fan cost and labor.

The $400 price seems awfully high. We had one put into our travel trailer about a year ago and the cost was less than half of that. We do enjoy the improved air flow.

Have 3.....One in bedroom, one in bathroom, one in living room

Bathroom is on exhaust and is only turned on when pooping or showering

Bedroom/Living room
One on exhaust/one on blowing air in
Both have thermostats that will open/turn it on based on temp set point then if/when temp set point is reached the thermostats will close/ turn them off

During the day...bedroom one blows in/living room one exhausts
During the night at bedtime...swap them around

Helps in 'warm' weather and small window open helps improve the 'breeze'

Works for us.......

We have one of them, not sure which brand, in our fifth wheel in the kitchen. We don't use it for cooling the camper, but it is super nice to have when we cook inside. We have not done that a lot, but it sure kept us from smoking things up when we made bacon for breakfast!
