What Louisiana asks of a build
Build for water and for the tape measure, in that order. The state takes 57.2 inches of rain a year and the number of very heavy rain days is climbing, so drainage, sealed connectors, underbody protection and a way to dry gear matter more here than any recovery kit. Then check your dimensions against the rules, because Louisiana publishes them. Wildlife management areas bar any vehicle with a wheel-tire combination radius of 17 inches or more, and the national forest caps trail vehicles at 50 inches wide.
Tell a builder which of the three systems you are aiming at. A rig for Kisatchie forest roads and dispersed corridors is a different specification from one for a Corps shoreline or a marsh highway, and in this state those are separate trips.
