IMHO start with the basics first. Load it as if you were going on a trip full water and fuel tanks clothes people etc. Then go it weighed four corner weighing is best but if not front and rear. If four corner make sure they are even right rear and left rear close. As mentioned by someone else set your tire pressures based off of the tire manufactures table. Make sure that you have at least 75% of the factory max weight on the front axle. After this then alignment and then start adding product to enhance your handling if it is still needed.
