2nd A/C and Fantastic

So, I am new here and new to owning a TT. I have had previous use of small RV's, just never owned any.

My TT is a Mallard M302. The front bedroom has a vent with no prewire. The bathroom has a vent with a tiny fan. The rear area is a kitchen/living room and has a 13,500 btu A/C in the "middle" and a vent with A/C prewire in the rear/kitchen. I do know HVAC and understand venting. I feel fairly confident I can fish wire where needed in the trailer.

My wife would like an A/C unit installed in the bedroom for when hotter weather comes. I would like to install a powered vent ( like a Fantastic) in the kitchen as well as replace the unit in the bathroom.

In the interest of simplicity, it would seem easier to put the A/C in the kitchen (giving me two units in the same area) and installing the Fantastic in the bedroom to help bring the air to the bedroom.

I do have things to look into as far as getting the best from the current A/C unit, like I have found where the factory ran a wire through the styrofoam near the bathroom register to get 12v to a light in the bathroom. They didn't fill it in so I have a leak into the roof as well as reduced airflow down that one side.

Any suggestions or experiences. The second A/C unit will probably happen one way or the other, so opinions on setup given what I have would also be appreciated.
  • TT is 50amp and pre wired and ready for second A/C in kitchen, right next to the one in the living room (same area). The noise is what the wife does want. Someone on another site suggested trying a box fan first which is a good idea, just unsure of where to place it giving the space available.

    Before you drop an AC in any of those vents, contact the manufacturer to make sure that the vent was framed to support an AC. While a vent would have the correct size to accept an AC, it may not have been framed in a way to support a 75-100 lbs AC unit on top of it.
  • I have just installed a 2nd AC in the bedroom, cut a hole in the wall above the bedroom door, and installed a fan to move air around.
    If you use the Fantastic Fan, you will blow lots of cold air outside and pull in lots of dust and dirt.
    30Amps runs both of my AC's but nothing else.
  • Several things to consider. First, many people do not like an A/C in the bedroom. It is too noisy. Secondly, if you only have 30 amp service into the trailer, you may find that inadequate to run two A/C's at the time along with the use of other items like microwave, hair dryer, water heater, refrigerator, etc.
