Yes it is a different construction. The RPM belts are designed to hold together better under higher operating temperatures. High RPM will cause the belt to get hotter because of the friction against the pulleys. a long road trip is also going to put stress on the belt in the form of heat maybe noot as much heat as high RPM, but on a road trip that heat is going to be there for a long while on that belt. That will take it's toll.
The also stretch less when they get hot. less chance of the belt jumping or slipping. The RPM line of belts is the highest grade belt that Gates makes. It is a racetrack grade belt.

Nope, names not Kurt.. It's Kevin... No worries tho I have been called far worse 🤪
When I make a road trip I don't pull the tool box behind my car.. I will make sure that I have the essential tools to fix the stupid things that can happen. Like a coupling popping off one of the charge pipes. Removing a tail light to replace a burnt out bulb. replace an exhaust hanger without using a metal coat hanger... Those kinds of things. The jack would be to lift the car up in the event something gets stuck under the car.. like an unavoidable tumble tree.. or a retread... No way would you catch me laying on the ground on the side of the highway on the drivers side of the car in the breakdown lane. Not a chance in hell. so if something is stuck on the driver side I would not be able to reach it from the passengers side without lifting the car up.
That little compressor and can of fix a flat the car comes with. It's useless and simply takes up space. Ever seen what a tire looks like when it goes flat while driving at 60-70 mph? that compressor and fix a flat isn't going to fix that tire by time you get the car over to the breakdown lane and stopped. I would be surprised if the tire is still there...
Slow leak... that's what the TPMS is for. You will know there is a problem with enough time to get the thing fixed at a tire place. Ignore the TPMS light, sit on the side of the highway....
I would change a belt, or replace the upper radiator hose on the side of the road.. patch the lower hose depending on where the leak is.. simple things. While I could do a water pump on the side of the highway, I would prefer a parking lot at the very least

. I can replace a water pump in < 2 hours, never take the turbo out, disconnect the cat or unbolt the motor mount to lift the engine up. but only if I have the proper tools with me.
