The albatross began with his vengeance early with this one. While the VW-based Schwimmwagen was a largely successful amphibous vehicle and its larger sister the DUKW entertained a measure of success at Normandy and remains affectionately remembered today, the Ford GPA was simply not the cat's pajamas. In low-water fording situation, the standard Willys machine often did better, and the Seep suffered a fate not dissimilar from a painted ship upon a painted ocean. It wasn't exactly the answer to a question nobody asked, but it was maybe at best a hard C response to what at the time was a rather pressing query. Bruce, large Amercan truckage, 1. Seep, not so much.
