The rolling and floating trailer, or RAFT, is designed to be towed behind the Hydratrek vehicles. It has a 3,000 lb. land payload and 1,800 lb. water payload. It is extremely useful when the project or search & rescue operation calls for additional material and/or personnel handling. It connects to the Hydratrek via a pintle hitch, and it is made from the same marine-grade aluminum as the Hydratrek.
