Lets talk roof vents.

So there are a lot of options on the market and a lot of them are quite expensive IMO.

Ive managed to track down the create-a-breeze fan from Fantastic Fans for $104 USD. By far the cheapest options ive come across. It only has "exhaust" mode, not intake.

For those of you with switchable direction fans, is it worth it? Any other recommendations? Do you find it a good idea to add on the additional protector cover? Any issues with our curved roofs?

These basic DC fans are a simple two-wire setup. Reversing polarity should reverse the direction of the fan blades.

I'm going with the Maxxfan 7500K model. One at the front and one at the back of my 40 footer. Lots of different options out there though to meet just about every need.

My PERSONAL opinion is that roof vents are great in nice weather, but if you're going to be using it when it's cold out they're a real pain. When it gets below freezing they start to drip condensation, and when it gets into the lower 20's and teens, they freeze shut. If you have sense enough to go where it's warm, you shouldn't have any problems (we don't have that much sense - we go where the grandkids are).

This makes perfect sense. But how do you ventilate your bus in warm weather?

The Fantastic Vent is good equipment and if anything fails the company will replace the part/s free. Ours has multi speed and in/out but we hardly ever use it as an intake fan. I do like the multiple speeds though.

The add on covers are nice. Now I don't pay much attention to whether the vent is open in bad weather.

So, for those who don't put in a vent, what do you do? Plastic bubble? Patch it? What are the other common options?

I used to have a website address but I can't seem to find it right now. Google "RV Skylights". They have clear ones and smoke tinted ones. They are great for covering openings and allow great light to come in. Or just completely patch it over with 16-18 gauge aluminum.

Anyone who has bought/installed one of these Maxxair or Fantastic Fans have any issues with it not properly mounting due to the curvature of the BUS roof???

I just installed a MaxxFan 4000k vent on Monday. I cut a new hole in the roof and mounted it with no problems at all. The curvature wasn't really an issue. I chose to also use a cover so I can keep it open and running 24x7 extracting the hot air.
