Hey guys! New to the group. I have a 2005 gmc canyon z85 SLE 4x4. I plan on pulling a trailer almost every day with a lawnmower/equipment etc. I have narrowed my search down to an AAL. and a 2 or 2 1/2 inch one. My question is, since I'm hauling every day, would it be smart to totally replace the leaf springs with heavier duty ones. Or can I just a get away with a 2 inch aal. I do not want any sagging in the rear. Thanks for any advice!
