I installed the Heng's Vortex II fan on 2 different trailers. Once installed they worked well and move lots of air.
The first install was real easy. All done from the inside with a screwdriver.
The second install was not easy because the Vortex II was not compatible with the roof vent that was installed by the RV manufacturer.
Look carefully at the installation instructions to make sure it will work with your roof vent. On my second install I had to replace the entire roof vent first. Up on the roof, remove, scrape sealant off, replace with new vent, and put on new dicor sealant.
One other potential downside is the Vortex II uses a big resistor to slow the fan speed down; this won't be a problem when attached to shore power. But if you are running off your batteries, be aware that the fan will always consume full power, even when set to a lower speed setting. If you switch to a PWM controller you can reduce the power use, but if you do all that, you may as well get the Vortex I and upgrade with a PWM controller and a switch to reverse direction. Same end result with lower cost.
