Too many miles on truck before long trip?

Our k2500 Suburban has 198,000 and we dont hesistate to take it anywhere. Its still strong. The body is starting to go on the rear door and down low. We have broken down on long trips. Unexpected issues and both times found a nice chevy dealers nearby who helped us out. The last time they had to order the part so I called the cg and let us back in no problem. They air frieghted the part in. Next day limped up to the dealer with the TT and fam. Unhitched and they proceeded to play games and have lunch in the parking lot while it was repaired. We continued on after that. If its gonna happen it will happen on the road or close to home

You know your ride if it feels and sounds good and you trust it, take it.
