Can you post the start/end cities?
I feel like you're getting some decent advice, but not the full picture I got when I joined the Tesla Community a year ago.
I own an SR+ with a rated range of 240 miles. The most I have gone on a segment is about 190 miles.
In general, you start a road trip at 90-100 from home, drive to about 20%, less if you're trusting, and refuel only to 70-85% depending on how far stations are in your area.
Your first segment will be longer due to charging at home to a higher %.
The rate at which you can recharge varies based on your cars state of charge. Charging at 25% is MUCH FASTER than charging at 75% and you can see this on the dash screen when you start doing this. it ramps down drastically.
So your trip may have more stops, but be faster overall, if you only ever charge from 20-60/70 on your trip once underway.
So a Long Range, which is rated at 322 miles, your first charge should get you around 250 miles. From there, you have 355 miles remaining. Since you have to make a stop regardless, you can either mid-point this around 175 and refuel to about 200 miles (65%) and then do same at the second stop. Both stops will be quick, and you will arrive with about 20% charge, so you'll need to top off there somewhere (destination charger perhaps) before you can do much upon arrival. If you need to have charge when you get there, get extra on that last charge.
I've never heard of this Go Anywhere app. Most people love the ABetterRoutePlanner.com website.
Since I don't know where you're going, I laid in a route from Columbus, OH (Go Blue) to just past Memphis to simulate going through Lousville and getting in 600 miles. I guessed and set LR RWD Aero wheels, set the departure SOC at 95% and arrival to 20%.
It shows only 3 stops, Louisville for 17 mins, 16-60%; Bowling Green 15 mins 15-55% and Dickson, TN 36 mins from 15-91%.
Last hop is a doozy. Your miles between stops are 207, 113, 98 and 181 miles.
You can do it in 2 stops, but your total time stopped would be greater. That's all about preference honestly.
The Tesla nav will guide you and you don't need to do any of this planning. it will auto-update as you drive based on conditions and you'll never go wrong. The only downside is the Tesla app will def do only 2 stops, which looking at this route, wouldn't be horrible.
In my SR+, I very rarely stop more than 20 mins, but I stop more frequently of course. This same route for me shows 5 stops, averaging 100 miles between for a total of 88 minutes. Your LR shows 3 for 68 mins.
The stops are "easy" plan to eat your meals and use the bathroom at those places. Park, immediately plug in, then take your time doing what you need to do. By the time you get back to the car, you should be done - except that 36 minute one, lol.
Your trip will go great! Have fun. Once you do it a few times, it all makes sense.
I routinely road-trip 800 miles from NJ to ATL. Let us know how it goes!
