All the advice here is good. As far as sand ladders go, you can be fancy or you can simply carry several pieces of 2'x 2' x 3/4" plywood. You'll get 8 our of a sheet and you can use them for all sorts of purposes such as getting unstuck, leveling out your trailer, putting under your trailer jockey wheel, cutting board, fire wood etc...all that for under $30. A deal.
