Since the beginning of time there have been discussions about whether there is/was/will be a 4500/5500 "Sasquatch" Ram. None have ever materialized (except for some sightings in faraway mexican forests). The whole situation is very much like bigfoot: lots of speculation, but no undoctored evidence.
Most scientists discount the existence of the 4500/5500 because the evidence supporting belief in the survival of a large Dodge Ram-like vehicle of such dimensions and capacity is scarce. The only notable exception is Grover S. Krantz (1931-2002), an anthropologist at Washington State University. For nearly forty years, Krantz argued for the probable existence of a Ram 4500/5500, but was unable to convince the majority of Dodge enthusiasts. The evidence for the 4500/5500's existence consists mainly of testimony from wide-eyed mexican tourists, tiretracks of questionable origin, and pictures that could easily have been of large Fords or Chevys with Dodge badges. There are no frame rails, no exhaust fumes, no body shells, no window stickers, no nothing. There is no evidence that any individual or community of such trucks dwells anywhere near any of the “sightings. ” In short, the evidence points more towards hoaxing and delusion than real discovery. Some proponents of the 4500/5500 myth ignore the lack of evidence and make wild claims of being visited in the night by phantom 5500's with big engines and GVW's over 30000 lb. Such claims reinforce the skeptic’s view that the 4500/5500 legend is a function of passionate fans of the paranormal, aided greatly by the mass media’s eagerness to cater to such enthusiasm.
In addition to the eyewitness testimonials of enthusiastic fans, the bulk of the evidence provided by proponents of the 4500/5500 consists of tire tracks and film. Of the few tire tracks available for examination in plaster casts, there is such great disparity in shape and configuration that the evidence suggests many independent pranksters.
Probably the most well-known evidence for belief in the 4500/5500's existence is a film shot by Dodge hunters Steve St. Laurent and Matt "Hole Shot Holset" on Oct 20, 1967, at Bluff Creek in southern Mexico. The film depicts a Dodge-like creature with oversized frame rails and a Cummins 8. 3. Its height is estimated at between 6' 6'' and 7' 4'', its weight at nearly 5 tons. Over thirty years have passed, yet no dieselhead has found further evidence of the creature near the site except for one alleged tire track. This doesn't stop thousands of devoted Dodge dieselheads from making the pilgrimage south every year in hopes of catching a glimpse of a Mexican tooling around a construction site behind the wheel of such a great beast.
Dodge, of course, has publicly denied the existance of a 4500/5500. They went so far as to publish an official report, called "The Red Papers", that quite handily counters all the evidence presented by believers of a 4500/5500. They claim most sightings of the 4500/5500 trucks are actually sightings of Caterpillar wheeled front-loaders or weather balloons.
The struggle continues...
