lineman,

Do you have the air suspension seats? If so, you can add an armrest to it. My truck came with both driver & passenger air suspension seats. The brochure on the seat implied that armrests were an option. Sooo, I e-mailed National Seating the number that's on the back of the seat base and they offered armrests for $29.95 each plus $10 shipping for both. I confirmed with an upholstry shop that my seats were rigged for armrests then ordered them from National Seating. Had them installed by the upholstry shop for $20 although you could probably install them yourself. As for the white knuckles on interstate driving, I don't understand unless it is just a bad section of I-40. I have only had my truck for 2 months but I drive at 60 to 70 mph mostly on 2 lane roads with no problems. I have a crew cab with 169" WB.
