What chassis battery cutoff switch do you like?

Thank you, everyone! I am persuaded that I should go with the in the cab version. Although it does sound like a pain to install.

Mex, did you intend to recommend that specific switch, or were you just giving it as an example? The Amazon reviewers don't seem to be very impressed with its build quality. Of course it is hard to know whether people know what they're talking about, on Amazon :-).

Have you used this particular switch?

Anybody else have when they recommend specifically?
