that stripmaster is way overkill - and note that nearly all the wires you'll be dealing with on a truck will be 10-16 gauge, nothing heavier except battery cables, and anything smaller won't handle any amount of current - also strippers for solid wire can be different than those for stranded, you don't want to be scoring a strand or 2 that will break off later - get a
plain simple stripper marked for the gauges and test it on some scrap to insure it suits the particular wire you're using, although skilled use of a knife can do the job well with practice
for connectors [which I'd think were supplied with the kit], use the best ones with the heat shrink sleeves, or at least ones with good nylon covers that stretch when crimped instead of the cheap plastic sleeve ones that get cut or break when crimped - and don't use tape except as a wrap for bundles, and even then expect the ends to come unglued over time - use heat shrink on terminal ends at connections - soldering connectors on is a good idea, but not a necessity if good connectors and crimpers are use with the proper technique
I should do a tech tip
about wiring
