4x4 F250 XL 4.30 axle vs 4x4 Sierra 2500HD 4.10 Axle looking for advice on which way to go. From my research it seems the F250 XL packs towing with other nice features in a kind of plain work truck like vehicle which I like well enough and the 2500HD SLE trim is a bit nicer. Not as worried about looks as durability though. Both with 6 speed transmission including heavy duty transmission cooler for both and for some reason the Ford doesn't mention HD Engine Cooler, but Sierra does list it specifically. Perhaps it's automatically included or understood in the Ford, but I could not find an upgrade option for HD engine cooler for the 6.2 liter Ford. The Ford is $4000 cheaper than the Sierra, and has factory goose/5th wheel and factory running boards. The both look very nice, the Sierra has nicer wheels, but no running boards or gooseneck/fifth wheel so that will make the Sierra cost even more. I would like to keep the truck for a very long time and will take extremely good care of it. This is a one chance to get it right investment for me and I could squeeze the extra money from somewhere for the Sierra but not sure it is the best choice. The Sierra does include the rear view camera and rear window defrost, but that only accounts for well under $1000 in the GM. The GM dealer says GMC is quality and Ford is quantity. I am sure Ford is quality too and if quantity or market leverage helps Ford offer lower cost quality items then as hard as I work for money I don't want to waste any. My brain is fried now from studying specs for weeks and I have narrowed it all down to this and it is time to pull the trigger. Neither dealer will reduce the price for me. It was like pulling teeth to get either to give me an extra $500 or so toward the deal. Ford's Truck Month isn't helping either and they sure aren't giving me 10 or 13k off of MSRP like their adds say this month. The Ford dealer told me it's like a loss leader ad where it only applies to 1 certain vehicle while quantities last and each dealership only gets 1 of the special vehicles so quantities won't last long. Yipes. Anyway... Sorry for the long story, but any advice as to which truck would serve me best as a long term investment. Needless to say, I do have towing needs. Perhaps the question settles on is the Sierra worth that much more money when Ford seems to be a great truck in wide use. Granted the Ford engine is newer, but I had trouble finding any negative reports on the Ford 6.2 liter gas engine. Likewise I had trouble finding significant negative comments on the GM 6.0 liter Vortec either. (As info, I am not going with diesel, hince the gas engines research) Can anybody help me? Thanks.
