Been there, done that...
Wasn't until sump number 4 I got round to getting one modded, the last time it happened was onto a single track road, so no way to avoid the rather large "hump" in the middle, heard it scraping along the road for a good half mile !, at the end of the lane I got out to see what the damage was, fortunatley it had just thinned the metal just to the point it was weeping, I made sure that all roads on the way home were as flat as I could find, was driving all the way home with my eye on the pressure gauge.... The 3 previous times I ended up on the back of a truck
Glad you got sorted with relatively little damage.
