Under-powered & transmission in Tacoma Disappoints
 Make sure you don't expect the mileage n the window. I have purchased three other Toyotas, and one in 2016, they have always met the mileage ratings this one fall s at least 20% below.  Transmission is seems to shift all of the time, and unless I am going down hill seems to really suck the gas.  The truck is clearly too heavy for the engine.  I had a Dodge Ram with a 318 back in the 90's and this is better than that but this is disappointing.  I added 200 lb fiberglass SnugTop cap and added two leafs under the rear springs because  when on highway on corners the truck pulled hard with the rear end suspension designed as it was on the TRD Off Road. I blame engineers that probably didn't drive this after they worked up the specs.  You should be able to make an off road that handles highway curves better.  I wouldn't buy the Tundra because the gas mileage is even worse.  In 1994 I had a 1989 Chevy Silverado pickup with long box not extended cap but was every bit as heavy as this truck actually heavier and would get avg 19.5 mpg, I get 17.3-17.5 avg on my Tacoma with Atkins cycle engine and thats with a lot of highway miles in that mileage.
