“During the 1920s Ford ruled the road and it is said that well over 2,000 aftermarket products and accessories could be purchased for them. The Lamsteed Kampkar body was one of those products.
Engineered by Samuel Lambert of the Lambert Pharmaceutical Company (makers of Listerine), the primary reason for its invention was because Lambert himself loved the outdoors and felt like suitable transportation would increase the fun!
The dimensions of the Kampkar body were developed so they would match those of the standard Ford chassis and according to ads of the day it only took hours to attach one. What a marvel. The 1921 Kampkar would comfortably seat six adults, provide sleeping accommodations for four, as well as hold blankets, clothing and even food. The Kampkar also had a folding table, a two-burner stove, an eight-gallon water supply, and a camping set in its trunk (consisted of cooking and eating utensils). Best of all? It sold for just $535.”
