, point-on, the OP did state he was in a Motor Home; I re-checked the forum / category before I first posted and figured, what the heck.
Agree with those who said, fuses, duct tape, etc. We actually roll a bit on the heavy side with tools and parts, our long-term goal to get back to a lot of extended boondocking. So what I had been thinking, what stupid part would be something I could absolutely positively not McGyver but didn't want to have to roll some distance for want of. And maybe with the "presumption" that there are a very few things that you just don't go anywhere without ... several gallons of DHMO
, spare tire(s), suitable breaker bar/lug wrench, did we already say Duct Tape ??
I like these sorts of discussions, it is amazing what others think of, and learn by experience, and share. As good as I am at figuring out new ways to break things, I will never presume to be any sort of authority, about the only thing I do know for sure, is that I will learn about more things that I don't know with each passing day.
