Ive had numerous gassers and 1 duramax. Diesel is AWESOME but unneccesary for me. Used to do some construction, sometimes hauled heavy loads like pallets of shingles, once in awhile some versa lock block, rented a few small mini-ex's or skid steers but now days i dont do much of that at all, and miss my diesel but dont need it.
also main reason is this was my first purchase of a brand new vehicle and the gasser was affordable with the options i needed and diesel wasnt. so gasser it was!!
in all honesty i dont even need a pick up, just cant be without one. spoiled myself with too many over the years and just hate having a car, plus if all works well i'll be a homeowner soon, so at that point in time my pick up will be far more useful and ill be glad i own one that i can make payments on for a few more years, have a warranty til its paid off then be able to rely on it solely on the fact that its never had an ass other than mine in the driver seat and i maintained it better than most could imagine doing so.
repairs and fuel costs on deisels don't outweigh the wow factor of owning one for me anymore.
