It came loaded with nearly every bell and whistle available. The only thing it doesn't have is the interior lighting option and the elephant ears.
It has the EB engine and 3.55 gears.
Right now there's only a few minor modifications on it and three of them were done by the dealer before I even knew it was for sale on the lot.
Current mods are as follows:
305 55 r20 toyo open country at2
Ford oem running boards
Dealer installed 2.5in leveling kit
Razor trimax 6in drop hitch
Weather tech digitaltech floor mats (tan)
Line-X platinum bed liner with premium top coat
Recon white lightning tailgate light strip.

Now that I have the truck I have a few questions that I'm hoping someone here has the time and patience to answer since searching on my own has yielded few results.
For starters, regular or premium gas?
For the tires I have, what psi is recommended?
Lastly, are CAIs or programmers worth it for getting 1 to 2 mpg gains? If so, any recommendations?

Thanks to any and all who reply.

In all seriousness..Congrats! Everyone else already gave you sound advice to your questions...I just hope you heard them with your little ears!!

I have a lifetime average MPG of 17.5 running 87 octane. I tried 93 octane once and saw no improvement in power or MPG. I bought gas at Sam's club once and lost 4 MPG....so quality gas is recommended!
