My painting contractor father is going to be upgrading hs 2002 toyota tundra sr5 4.7L 2WD access cab truck. Hes going to install a bed slide and ladder racks and other stuff for utitlity but i showed him some information on increasing efficiency and he was very interested. I dont know about the engine or gearing but i believe some aero mods should be pretty cost effective. The utility stuff will add some weight.

What is the estimated mpg saving i would get for doing the following.

He might replace the leer 122 hi cap on it with a utility cap. The leer hi cap slopes up 1 foot higher than the cab.

I might lower the truck a couple of inches if i get a good deal on a kit.

Rim covers.

rear wheelwell fairing.

air dam and side skirt

partial or full bellypan.

grille blocking

cap/cab gap filling.

Removing 3 or 4 long extension ladders from the racks. (Depending on the miles between jobs and the Cd it might not be worth the effort to take them off and put back on sometimes.)


What are the advantages of the $150 mpg gauge vs the $50 kind?
