Good story, and I sympathize with the roadside-repair-caused-hand-burning! Been there and done that, as I suspect many of us have. The simple fact is that things (to use a more PC word) happen. Yeah, maybe you coulda/shoulda/woulda changed those hoses the night before departing. And maybe one of those - or a different one - would have split. Or maybe not. Fate plays all kind of dirty tricks on us. The thing is, you noticed the temp rising and you were at least semi-prepared to fix things. Most people are not (which is why tow companies love being located near Interstate Highways).
Maybe a more important question is why you waited until getting ready for a 2400 mile trip before noticing the water balloons in the engine compartment? That stuff doesn't happen overnight. Regular, close inspection of hoses is imperative - not just when heading out for a road trip. In fact, I'm a proponent of changing out hoses on a regular interval, regardless of how they "look". Rubberized items are consumable, just like belts, oil, and other fluids - they get old and especially weakened by heat. It seems to me that the expense is worth it to change them all every few years vs. the potential (and sometimes very real) expense of a failure on a long trip! 🤔
Just today, as I was driving along, a really pretty BMW shot past me in the fast lane. Sounded good (my window was down). I thought, "Say, that's a nice rig - wouldn't mind having one of those in the stable." My pickup wasn't able to catch up enough to even spot the model - I just barely glimpsed the little blue and white circular badge on the rear deck before it got out of sight.
