I have a 2012 Access cab that I bought new.
I'm your size except a bit lighter.
For added seat comfort and raising you up in height in your seat, I bought Wet Okole seat covers.
They are worth every penny and are still good to go after 5 years. You will gain a lot more comfort using them,especially off road.
Second the Wet Okoles. Got the passenger side with the heater for my wife. It's the only way I can get her to ride in it.
