I don't think I've seen a battery powered impact gun mentioned yet. If the camper leaves my yard, it always has a 18V Makita Impact gun (and impact sockets to fit lug nuts). The one time I needed it, I was sooooooo happy I had it.
Yes on white duct tape and maybe black as well. I now also carry eterna bond due to an unfortunate tree scraping incident last year.
And for those who want to have it everything covered, I now also carry a code reader/scanner device that can clear those pesky emission codes when they come up and tell you that you're screwed in "XX" number of miles. Imagine traveling to the middle of nowhere and before you get there, you get a code that tells you that limp mode is coming up thanks to a faulty sensor in the DEF system. Not no more...
