Teardrops n Tiny Travel Trailers

Does anyone have any ideas or suggestions on what to use to vent a portable ac exhaust thru the floor. I've been trying to come up with something using pvc but could only come up with using a 4" cleanout. The exhaust hose is 5" flex hose. Any ideas would be appreciated. Thanks

I have the same size hose on multiple unit. I had 2 - 5" tunes made, ran them through the floor and put 5" adjustable elbows on them under the trailer to direct intake & exhaust.

marine deck plates. Make sure to screen against critters, and seal back up before travelling
