Sounds like you have a nice TV coming
I pull with an '11 F350 dually. No bags or anything and it squats a bit at the back when hooked up. I have lots of bed clearance. I have 17's but it's the tire height that matters as said above. Mine's 4x too, would be hard pressed to find a 2x on a lot up here in ON.
Be nice if you could order a vehicle item by item as you could way back in the day. Now if you want a single item added you have to buy a 5k$ package to get it.
