You will find this topic has been discussed a number of times before. If you can't find those threads using the WTW search, I suggest using Google and add "site:wanderthewest.com" to your search terms (without the quotes) that's way more effective.
FWIW I use the standard Yakima deflector on my Tacoma and it works quite well.

Have the same thing on our 05 Tundra and ATC Ocelot. built an aluminum deflector, used it for two years. Took it off, no change in mpg. But I rarely drive over 65.

Seems like no matter what you do to smooth out a camper profile the mpg just won't budge nearly as much as it does when you drive slower. I guess this is why semi-trucks all go about 68-70 mph. 65 mph is a good spot, but I often find myself saying "screw it" on the way home and do 70. Pulling a trailer is even worse on mpg.

I have a Yakima wind deflector too. Didn't do anything for mpg, but keeps most bugs out from that hard to clean area behind the cab.

I made one for my previous rig (F150 + 2006 Hawk) because the gap between the top of cab and camper seemed too much. My current rig has a smaller gap and I use the windshield as a deflector. Works pretty good at subsonic speeds.

I read an article about all the aerodynamic mods made on big rigs. At best these help fuel mileage increase by 1-2%. So on one truck you might not notice it, but when you have a fleet of 1000 trucks it starts to pay off.

Another article said testing often showed small benefits under certain conditions, but throw in variables like a crosswind or wind from an oblique direction and things like fairings, skirting, or air tabs may or may not help mileage. So, we can all give these things a try, but they may or may not help in all conditions.
