Deflectors

Any opinions on wind deflectors. I was looking at the Aero Shield Wind Deflector for a Chevy 3500 dually. For or against?
Thanks, Total Bliss

I just read a big article on this the other day. In reality, due to the distance from the wing to the front of the RV, they don't do much good. They may even make things worse in regards to fuel economy. I always liked the looks of the polished stainless wings on top of the dually, but never have installed one.

I'll have to dig again. I think I got it from one of my bored moment google searches. If I can find it again I'll post the link.

No references, but I've heard the same thing - if there is a difference, it's so nominal that you won't make up for the cost of it.

Well, as usual I can't find the article I read doing a search again. There are tons of debates on those things. Most say something along the lines of what ependydad said.

Deflectors

Thanks for the advice. That will not be on my after market list.

Had one years ago mounted on the rear 3' of a cab high topper that I adjusted to an angle where it would deflect all the bugs, etc off the camper. Whether it helped gas mileage or not I have no idea as I never pulled the camper without it elevated. When not pulling the camper, it would lay down flat on the topper. It was made out of the top 24" of a semi deflector.

The rather lengthy article I read about testing one indicated that it would have to be the width of the trailer to even begin to be effective. The most cost effective things are enclosed under body and a boat tail rear. Plus many newer fifth wheels are fairly aerodynamic to begin with. Think "round corners".

The one I had years ago came off a semi tractor and was not cut down width wise, it had curved sides/edges and did keep the bugs off the entire top of the trailer. I did get bugs on the lower 2'-3' that wasn't shielded by the truck itself. Being mounted on the rear of the topper, it was only about 4-1/2'-5' from the top of the deflector to the camper.

Got any pictures of that set up OC? Sounds interesting.

The eternal quest - better gas mileage. Give up - there is no easy or any way to greatly improve your gas mileage. Some fairly expensive modifications will make differences that are barely noticeable. If you are going to move a 10,000 pound barn door down the highway at 60 mph it just takes that much fuel.
