@VegasBella have you ever been stranded due to charging issues?
No I have not.
I drive regularly from Vegas to the LA area and regularly now from Vegas to Phoenix. I've also driven Vegas to Denver in my Tesla.
My suggestion is to set the range to percent rather than miles. And to arrange your travel so you don't get below 10%.
BUT... things can happen and I have felt a close to being stranded. Examples:
Last Summer on a trip back to Vegas from SoCal I received a warning about not being allowed to charge in the afternoon due to power outages/restrictions. So this basically meant that I had to charge up to 100% at my first SuperCharger rather than distributing my charges between two SuperCharging stations. And charging from 70-100% can take a really long time. Going from 20-70% is fast. But then the rate slows and it just feels like it takes forever. I was bored and annoyed having to stay there for sooo long (like 2 hours I think). And it was just sooo hot so I couldn't really go for a nice walk or anything.
Recently this Winter between Phoenix and Vegas there were serious storm warnings and hubby and Google thought I should take an alternative route than my usual. That meant added miles which also meant added charging so time added for driving AND for charging turned a 5-6 hour drive into a 8-9 hour drive. But mostly there was that surge of worry when trying to figure out the navigation of where to charge because apparently the Tesla navigation did not agree with Hubby and Google about an alternate route being best. So I had to figure that out on my own. And what was worse, I wasn't even able to avoid all the ice. But I still got enough charge and wasn't going to be stranded due to my car being EV.
In other situations I've had to slow my speed to 65 to maintain enough charge to get to the next charger. I'm always worried about what would happen if my next charger doesn't work but luckily that's never happened without warning. And now I'm seeing more chargers added along my routes so it wouldn't be as big of an issue if it did happen.
And a few times during peak use I have had to wait in line to charge. It adds time to my travel day and it's annoying but it's usually just 15-30 minutes added, not hours.
And twice I've been "iced" which is where an ICE car (gas car) parks in your charging parking place to block EVs from charging. But luckily those times I have found alternatives.
