Arrowhead actually manufactured travel trailers. In 1960 they ventured into the mobile home branch and immediately ventured right back out. They homes came in 50 and 55 foot lengths and ten foot wide.
They were so accustomed to building travel trailers that they carried the method over into their mobile homes by advertising the weight of the unit. This was totally unnecessary for a mobile home buyer to know, but
necessary for the buyer of a travel trailer.
