I met Fred and Elisabeth when they were driving around the world in their Ponton.
https://classicstrider.com/ They had many many spares and were towing a small camping trailer. Like extra shocks, many tools, on and on. All stashed away in the fender wells inside the doors and any extra space available. While they were driving out of town, their rear diff grenaded. Got fixed here at MBI, but all the weight on an under engineered car is
no bueno.
I bring a few spares, but am happy to hitch a ride out to a shop or get strap towed if needed rather than carry 500# of spare parts. Having driven an old VW for many years of travels, a non-catastrophic breakdown is just part of the adventure and can lead to unexpected but interesting experiences.
