Interesting take, but I have to disagree. That snowplow hit probably would have wrecked the cheap bumper too, but the shopping cart cracking in two weeks is just bad luck, not proof the part was garbage. I have used economy bumpers for years on my old Silverado and they held up to worse than a cart tap, including a deer strike that did more damage to the deer. The real difference is fit and finish, not impact resistance, and for the price difference, I will take a few scuffs over dropping four hundred bucks every time. The OEM stuff is nice, but paying triple just for a clear coat buffer is a luxury I cannot justify.

Reminds me of a camping chair that snapped on flat ground.

That old timer might have gotten lucky so far, but 180k is nothing on a diesel. Jake brakes are made for braking, not idling, and keeping that much pressure on the exhaust valves all night just heats things up without any real benefit. Turbo stays warm enough on its own with a simple high idle or just letting the truck run for a minute before you roll. A rebuild costs way more than a little extra fuel to warm up proper.
