Thanks for the replies! My truck is just leveled right now, but may possibly go up to 4in, depending on how i like it with another leveling kit added on. Im debating going up in the front 2 or so mor inches, or dropping down to a 2in block in the rear. I only rn 35s, and will probably keep it that way, as it seems 37s drop down to a d rating, and my trailer is pretty heavy. I will start looking for better single shock options.
