Robert, the Ford was a bought new 1989 F150 standard cab long bed 4x4 custom ordered with HD front suspension with quad shocks, HD rear suspension, over ride rear springs, camper and towing packages, roof lights, HD front and rear anti-roll bars and dual tanks. Engine was a 302 (5.0 L to you metric people), 5 speed manual transmission and 3.55:1 open differentials. Should have been good on gas, but it was a gutless pig.
Paint flaked off in huge hunks after the warranty expired. Almost to the day. Local ford dealer shined me on so that I couldn't get it repainted by ford. None of the frame or suspension was painted or even coated. Any place that salt could collect, it did and rust followed happily in it's wake. Around the fuel tank doors, wheel well arches, under the doors, etc. I forgot to mention that the main leaf spring on both sides cracked completely in half. Took some doing to change them out at -15F laying in the snow at night. Ford's front end had some sort of polymer mounted ball joints and no grease fittings. The poly pounded out so the front end would take a "set" when you made a turn. So you would have to over correct to pop it back. Very annoying and hard to drive straight. It also ate u-joints about every 15,000 miles, rear seals about every 20,000, brakes went about 50,000 but they needed new drums, at 60,000 the parking brake cables rusted shut when the truck sat at the airport in January. Wasn't happy sawing the cables in half laying in the snow wearing my suit, but I did want to get home.
On the window cracks, I have seen several where the window frame snaps off of the door. Each of the people that owned the trucks '97 and 2 '98's closed the doors by pushing the top of the window frame. One guy was closing the door and stopped it from closing and the frame snapped in his hand. Cracks don't just start then stop - they are like weeds - they grow and grow.
And just to set the record straight - That truck was either the 15th or 16th ford that I bought. I still have 2 old cougars and an old mustang and there aren't many nuts or bolts in a ford engine that I can't ID, so I am not a ford hater. But for trucks, Chevy has been much better than ford both for reliability as well as performance. According to my records, about 25% of the total miles on the Chevy's has been towing 9000-9500#. Not a huge load, but enough to tell. I don't have any personal exp with new ford's and the hub-bub around the 6.0L diesel has pushed me farther from them - so the new ones could be perfect and I wouldn't know.
As they say, YMMV.

Oh on topic, A buddy sold one dakota at 85k and it went 240k before it was sold again. No engine or trans issues with it. That was a 6 cyl. He went to a 4.7L v8 after that and had good luck there too. He has been hemi in a full size ever since. I know that he towed 10k several times with the dakota. Probably shouldn't have, but he did.
