12V Electrical wiring - wire nuts vs crimp connections

When I replace crimp connections that are exposed to the elements on a trailer I find that I have to cut back quite a bit of cable in order to get to good, un-corroded copper. Way more than if the wire was protected from the elements with a good waterproof crimp.

If it needs to be cut it can be cut right at the crimp and should have good copper and not need to be . If there's some concern about length, add wire to make a service loop that can be shortened as needed.
