Are you gonna pull those pistols or whistle Dixie?

What I have never seen with a trailer is a lug wrench. All my trailers had spare tires but not one with a jack or wrench to change it roadside. Lug nuts on the wheels are typically a different size than the nuts holding the spare. I wouldn't expect the dealer to include a jack & wrenches (that's why we all carry so many tools). Just saying this is more important than water filters and surge protectors.
