Prinsu MPG?

Looking into getting a Prinsu roof rack. For all of you who have one, how does it affect your MPG and how is the noise?

 

Really depends on a number of factors. MPGs, I noticed no difference and I have an ultraguage monitoring that. But I'm also lifted, with a bedrack and RTT, so my MPGs already took a big hit. Noise really seems to be dependent on the vehicle and the driver. For some reason, some trucks have gotten a whistle, but this seems to be the exception and not the rule. I have no whistle with the deflector on the lowest setting.

Also, I think some drivers tend to be more annoyed by noise than others. When you put anything on the roof, you're going to get some wind noise. I noticed mine at first, but after a week I don't even hear it anymore. Radio covers it completely and even when it's off, you can still have a normal conversation with passengers. You're not yelling over it at all.
