This file creates a late 1940's era Fruehauf tanker, at 33' scale feet long. The prototype details are as best as I can interpret from researching the movie 'Duel' and trying to replicate it as close as possible.I also offer a Peterbilt that has all the 'Duel' specific details like the bumper bar, swamp cooler, small horizontal air cleaner etc In the movie,the trailer was pitted, rusty, dirty etc, so I have created this file to work in the basic material. This file has passed the normal software checks, but should there be an issue contact me via the designer link, or via email to Steve Nasburg at modelmechanic@gmail.com
