LEER topper weight? Mpg difference?

dose anyone know how much a leer xr weighs? experienced any power loss up hill? or having to really step on it to get it going? will adding a camper shell help my pre runner hook up a little better in snow with chains?

 

Since it's fiberglass, I wouldn't expect it to weigh much. I also don't think you'll have much power loss at all uphill.

I'd still put sandbags or cinderblocks (more weight) in the back with a PreRunner in the snow, to get more back end traction.

 

I haven't noticed any power loss with mine. They're not that heavy, only took two of us to remove the topper from my full size Dodge and set it on another truck. LEER should have the specs on their website.

my leer weighs 200 lbs thats what they told me. truck still runs with same power. lost about 2 mpg with the rims and topper

 

Seems like a lot of mileage to loss. Do you attribute it more to the wheels than the cap? They say the cap is supposed to help mileage.

 

maybe its just the wheels and lift. last time i checked i got 294 miles before light came on i want to see how many miles i get on this next tank

 

My question would be how is the OP tracking the milage- If the rims/tires are a difference size that'll change your mileage reading/gas mileage. Between a lift with new tires and the weight from the cap I can see 2 mpgs...

 

No significant mileage difference from mine (still have the stock Dunlops).

my mileage sucked before i put the cap on and still sucks after. i stopped caring about my mpg.

 

I didn't notice any decrease with mine, there is less drag. I fill up about every 300 miles +/-

 

Actually the topper will decrease gas mileage. According to Myth Busters, these best thing you can do for gas mileage is to leave the tailgate up.

 

I saw their test on the caps. It was very unscientific and frankly I think quite flawed. I am not sure if the extra weight of the cap offsets any improvement in aerodynamic drag.
I certainly don't think a tailgate up helps mileage, that would debunk all the advertisements for tonneau covers.

I odered a cab high fiberglass cap today , so I'll report my mileage findings.

 

Is this topper youall are talking about the most flush one there is for tacomas? I want one that looks really streamline with the truck- kinda like an SUV apperance!

 

You can get the cap/topper/shell in many heights from cab high to much higher. I also prefer the cab high model. Check them out at leer.com

 

Yeah- Because EVERYONE advertises the complete truth.

The trucks are designed to run without covers/caps/devices...so I'm going to go with they are reasonably efficient as is. Start messing with that air flow you are GOING to turn laminar into turbulent flow and that induces drag...

 

Check out my pic's

 

here is a good place to show that great top off!!

I had my shell on for 1 run of a tank of gas. It improved my mileage by a little over 1 mpg. I had to send the top back to get new windows. I'll pick up more runs to get a more accurate count when I get it back.

I use the same pump, on the same setting, at the same time of day...blah blah blah.......I'm ocd with my MPG.........

 

From what I understand, a tonneau gives the most improvement in mileage. A cap reduces it because of the amount of turbulence it creates behind the truck. No tonneau and leaving the tailgate down causes more turbulence behind the cab. With the tailgate up, there's a slight improvement, due to it causing air to swirl in the bed, acting as a cushion and helping air move more quickly over the bed.

I didn't see the Mythbusters take this on, but more often than not, their testing is very flawed.
