what to do what to do

[TN70C10]

My 70 has been bagged for the past few years. Its was cool for a while but im tired of it now. So , im going back to springs. I really want to go with a 4/6 but I use this truck to pull my bass boat, 17ft fiberglass with 150. So i asked ece they recommend 5inch. What im wondering is there anyone in here that uses there lowered truck to pull a boat with? Airshocks? I do have the shock relocators also extreme drop crossmember, super track bar, 1 pc driveshaft. I use a 3 inch raise on the hitch. Just wondering if someone can tell me about there situation before i get into mine. The lake is 10 min down the road and i have no intention of trying to do and long trips. Thanks.
