When a headlight, any headlight, is designed the first decision made is which bulb to use. The headlight is then designed around the physical and optical characteristics of the bulb.

It is important to note that a halogen bulb is optically very different from a HID bulb.

The filament of the halogen bulb is (usually) about 5mm long, is straight, and produces a single hot spot of light in the very centre of the filament. The hotspot is considered a pin-point light source and the physical halogen headlight is designed to capture and focus light emanating from the single pin-point light source.

The HID discharge arc is approx 5mm long, is curved, and has two distinct hotspots. The hotspots are at either end of the arc (at the electrodes) and are 5mm apart. Each hotspot is a pin-point light source. The two pin-point light sources of the arc are 5mm apart. The physical HID headlight is designed to capture and focus light emanating from two distinct pin-point light sources.

The optical incompatibility of the halogen headlight and the HID arc arises because the halogen headlight is not designed to work with two pin-point light sources. It can only work with a single pin-point light source. So what happens when a HID capsule is used in a halogen headlight? If the manufacturer of the rebased HID bulb is extremely lucky one of the two pin-point light sources will align with where the single halogen bulb pin-point light source should be and all is well. Well, not really. All is well until we consider the second pin-point light source of the arc. This is going to create havoc with the light assembly's abilty to capture and focus light. The halogen assembly, in effect, does not know what to do with the extra light. In reality what happens is that the halogen assembly, even a halogen projector assembly, is going to start spewing light where it was never intended to be spewed. This is the glare that ALL, repeat ALL, halogen headlights generate when used with rebased bulbs. Some generate more glare than others but they ALL generate excessive glare. Even the headlights in your truck do so, and they do so whether or not you're willing to open your mind and accept it. Some halogen assemblies will glare more than others when used with a HID bulb but they ALL glare excessively. There's simply no getting around the physical differences of the two bulb types.

More often than not neither of the two arc pin-point light sources are going to be aligned with where the halogen bulb hotspot should be. This creates even bigger problems and usually a lot more glare.

So what about the vendors that claim their rebased bulbs are aligned to halogen specs? The vendors are either lying through their teeth or they're totally ignorant of the differences between halogen bulbs and HID bulbs.

So I've answered your question and I have no intention of arguing the point any farther with you. I fully expect you to come back and say how the laws of physics are wrong and how the rebased HID bulbs in your truck don't cause problems for other drivers. Feel free to continue living in la-la dream-land while claiming that your setup is different from any other rebased bulb setup.

I have personally tested dozens and dozens of halogen headlights, even the type in your truck, with HID kits and not one of them did not generate excessive levels of glare.
