i use my truck, and i mean use it. granted, it's a v6 with 1/2 ton springs all around, but it puts in work. with all my tools or materials i can be carrying 1/2 ton no problem. that plus driving it in heavy, hilly seattle traffic, i will tell you honestly- if you aren't the one driving it (i used to drive the company work truck
), and it is under load, and you are at all worried about it, just keep the oiul change intervals at 3000 to 3500. it may cost a bit more, but the peace of mind is worth it. ryan
