How to Install a 2nd RV Air Conditioner Unit in a Work and Play 30WR

After a trip or two through the Southwest or a jaunt through Florida at the right time of year will tell you everything you need to know about your RV air conditioner needs. Depending on your particular RV model you may not have enough RV AC units or possibly not one at all. If so then this post is for you. You may be curious what goes into adding or replacing a RV air conditioner unit because you have simply had enough of the heat.

Doug, from Astoria, Oregon felt like many do, one AC unit just didn’t get it done. He is the proud owner of a Forest River Work and Play 30WR. If you aren’t familiar with 30WR it is a traditional tow trailer toy hauler. He decided to add a 2nd RV air conditioner to the garage area of his 30WR. He had been interested in adding a AC unit for a while but the cost was prohibitive till he caught a deal he couldn’t pass up on craigslist.

Fortunately for Doug, his toy hauler was pre-wired from Forest River for a second RV AC unit which included its own circuit breaker and junction box. To start Doug had to remove the vent that currently sat over the opening in the room where the AC would go. The pictures begin to tell the story below.

The tools that were key for adding a 2nd Air Conditioner:

  • Putty Knife (Doug used it for several tasks)
  • Cordless Drill
  • A fork lift or several friends to hoist the RV AC unit on the roof


Clearly there is much more that went into this project but we thought this offered a inside look at what goes into installing a RV air conditioner as well as what to expect before trying it yourself. The reality is if you are handy and can get a deal on a RV AC unit then you shouldn’t have too much trouble if you were lucky enough to have your vent cutout pre-wired for AC (not as common as we would like). If you are considering adding a air conditioner to your RV then please visit forums for more detailed information and additional photos.
