Charles “Chuck” Prater’s (1928-1913) jeep camper has been discussed in the past, but pics of his prototypes are less well known. Chuck must have been a curious kind of guy, because when he was an employee at the circulation department of the Palm Beach Post in Florida he invented an automatic paper bagging machine.

How he got involved with jeeps isn’t well documented, but in the 1960s he developed a unique camper setup that allowed a camper to be ‘hitched’ to the back of a CJ-5. He showed off his prototype to the Palm Beach Post in July of 1968:

July 07, 1968, Palm Beach Post, Palm Beach, Florida.

From the CJ5camper.com website we have this additional photo of the prototype, year unknown. You’ll note that the camper in the pic above seems to lack the blue color added to the pic below, so this may have been taken after the Palm Beach Post photo?:

The Palm Beach reported a few months later on September 25, 1968, that Kaiser-Jeep agreed to manufactured Chuck’s camper idea:

For reasons unknown at this point, Chuck waited almost two years later (August 24, 1970) to file his patent (approved August 15, 1972). The patent included several illustrations. Below is one of them.
At some point after he filed his patent, Waldron Motors presented Chuck with camper #1. Curiously, the caption indicates he patented the idea, then sold it. However, the information above suggests he sold the idea, then patented it?:

This newspaper clipping was posted to thegentlemanracer.com’s site.

Being the inventor he was, Chuck didn’t stop inventing after the development of the camper. He expanded on  his basic camper invention with a similar dump trailer idea. This article comes from the cj5camper.com site and is undated:

I searched but could not find a patent or another other information about the dump trailer.

According to his brother-in-law Sam Williams (see his comment in this post), Chuck built another camper that fit the CJ-7, one which Sam owns.
