  • Don’t forget to think about how to keep the salt air from corroding the electronics. Either build a spare or two that you keep sealed in plastic, or find an airtight case with an integrated heat sink or something.

    Edit: you might want to look into conformal coating and dielectric grease (for the connectors) as well, although I don’t know enough about that to competently give advice beyond the mere suggestion.








  • Every definitive trait has some counter example that still counts because people “feel” it’s good enough.

    There’s an aphorism in statstics / science: “all models are wrong, but some are useful.” I feel that the distinction between genuine off-road-capable SUVs and crossovers/tall cars/glorified station wagons or minivans is useful, even if it isn’t completely definitive. Generally speaking, if it’s a unibody vehicle it probably isn’t very good off-road, and therefore doesn’t really deserve to be called an “SUV.”

    So does a 2wd “suv” (by your definition) then get declassified?

    A 2WD SUV is less general-purpose, but I think they still have enough potential to count (think desert-racing prerunners, which are often 2WD but legitimate off-road vehicles).


  • Plenty of large “tall station wagons” are unibody. About the only legitimately capable offroad 4x4s I know of that are unibody are the Jeep Cherokee (the old one) and maybe something like a Suzuki Jimny (edit: nope, even that tiny thing is body-on-frame).

    (Consider the difference between a (unibody) Toyota Highlander and a (body-on-frame) Toyota 4Runner, for example: only the latter is a “real” SUV, in terms of being capable off-road.)
