I will say the adjustable peddles are nice if there is more than one driver. My father and I went on a hunting trip to our cabin for a couple of days. Since its a five hour trip and he worked that day I took over at the half way mark. Since I stand almost 6'1'' and he is 5'9ish'', wow. I cant stand having the seat back the whole way because my arms feel like stretch armstrong. so i was able to find a happy medium by adjusting the peddle to meet my standards haha
I've never whined about any extra options that I thought I wouldn't use. Mainly because I saw a truck and fell in love, so I tried to rationalize spending 42k on a truck with lots of options I probably wouldn't use. Turns out I love the adj peddles because I'm oddly shaped (long arms, short legs). I love my dual automatic climate control, It hasn't moved from 70 since I bought the truck. I could do without the back up sensor because I leave my trailer hitch connected making it very annoying having to turn it off every time I start the truck.
I don't adjust the seats on my side, but my passengers are always loving that it's power passenger side. I do use the bluetooth for my phone, I use the steering wheel controls every day, I even use the iPod/iPhone connection inside the center console! All in all, I use everything except the parking assist.
