I've had mine since 2010 and have a few improvements.
I would like a luxury package with heated seats and steering wheel, a moon roof, automatic climate temp control, power seats, more interior lights like on the doors, trip computer, dampered tailgate drop down like the tundra, and power rear window. Could make the truck expensive but I'd be willing to pay for it.
I cannot see the display on the radio during the day with polarized sun glasses.
ALL knobs and buttons need indicator lights to tell you if they are on or off.
Lights in the bed where the 3rd brake light is.
Front and middle D-loop tie-downs in the bed.
Locking fuel door.
USB and 120V AC plugs inside the cabin.
Built in brake controller for towing like large trucks.
Much larger backup camera screen. I only use it when backing up to a trailer and with my reader glasses on.
250 Amp alternator to run a 1000 W inverter with out battery drain.
Things that don't bother me:
Ticking engine. I couldn't care less.
I have no complains about looks. I could even use MORE chrome.
It's interesting that some are complaining about power. I think it has more than enough. It's not a sports car but will hold it's own if needed. And this is without a SC.
