If I install Air Tabs & Solid Aero Hubcaps will I get 10 mpg

Just a thought, has anyone done this yet..

No, but we have stayed in a Walmart or other overnight for a tremendous savings in fuel costs and the same as getting more MPG and less cost per mile.

IMHO if you are not getting 10MPG now, the only way you will is if you drop it out of a C130 at 10,000FT with a tail wind.... :W

The best way to improve gas mileage, especially 10mpg or more, is to only drive DOWN steep hills with a substantial tail wind of say 40mph or more...:B...Dennis

Look at what the pro's are doing for your answer. The trucking companies use wind wings and sometimes trailer tails to get better mileage, but I've never seen airtabs on a semi. If they could get a couple tenths of a mpg from airtabs they would be on lots of OTR trailers.

Most people wouldn't notice them if they weren't looking for them. They are on a lot of semi's. All you have to do is look.

Take a toad with you. The increase in drag may cost you 1 MPG but you are now taking TWO vehicles from point A to B so your mileage essentially doubles. :B

I think this is the best way to increased over all MPG, but I never see a post about this. I usually put as many miles or more on my tow car as I do on the MH. I get 8.7 MPG on the MH and 40 MPGS on the tow car. I average 23 mpg on this combination. This will be more economical than driving any large SUV or Jeep that gets 18 mps to go from point A to point B. I see no change in MH MPG when towing or not.

I've read posts over the years where folks are attempting to improve MPG. Banks Systems, Headers, Gearing, Wings...etc. $1000,$2000,$5000 and more.

Results are a 1 to 4 MPG on average improvement. Seems like a lot on money for little improvement.

Like Goldencrazy posted...shortest route and light throttle.

The value I get from being in the outdoors enjoying what nature provides far outweighs the travel costs.

When I started towing a Smart Car my average mileage improved. It had no impact on my motorhome mileage and I stopped using the motorhome (at the time a 27 ft BT Cruiser) for sight seeing trips. More and more we parked the motorhome and drove the little car. After a year of some big trips I looked at motorhome miles and toad miles and the mpg for both. It was a year we went to the Olympics in Vancouver and Alaska so big miles on motorhome. My average mileage between the two was 28. If you factored in the miles of towing it went to 39. These numbers may be slightly different and memory may be off but motorhome was averaged at 8mpg and car at 45mpg. Bottom line is if you want to get your best mpg on motorhome view it as a house on wheels and not a large car. Find the shortest route and drive at a reasonable speed. Finally I don't want this to sound like obsession with mpg. It is to be fun so what if we spend a little extra on fuel. Put in 40 gallons at total of 72 bucks in Tucson yesterday.

Hi,

Air tabs reduced the noise levels during driving in my Class C. The back does stay cleaner. Mileage increase is not measurable.

Can belly pans be retrofitted?

I had air tabs on my 40' fifth wheel race trailer. I saw no measurable mpg improvement, but a buddy following me said that my trailer did kick up more road dirt & dust than usual. For whatever that's worth.

I don't know about the solid wheel covers. I suppose in theory they might help.
