Bad mouthing peers and competitors actually damages you.
about the fridge, what about the following:
1) you know exactly which component needs to be replaced
2) you have a plan where you are when
3) why not try to find a place that fixes your fridge for free, give them enough time to get hold of the component and drive to them with your travel trailer when you are on the road anyway, of course assuming such repair places are close to the route you would take anyway…
