Properly done crimps are gas-tight and provide more consistent and reliable connections than soldered ones. They're also less subject to failure when used in environments subject to vibration.

Crimping is an efficient and highly reliable method to assemble and terminate conductors, and typically provides a stronger, more reliable termination method than that achieved by soldering.

I'd trust some guy getting minimum wage to properly install a crimp long before I'd trust them to do a proper job of soldering.

Your also talking about a company that gives the job to the lowest bidder!

And I`m not talking about putting a vehicle into to space, I`m talking about a battery connection on an RV. Crimping is faster than soldering, so that is another reason they do it.
I wouldn't trust a guy making minimum wage to do anything. They couldn't even get the speaker polarity right on my trailer. But that doesn`t matter, we are talking about doing it so it works right and lasts forever. I`ve never seen a solder connection fail in the automotive/RV world! I have seen many crimp connections that have, both by hand and machine.
