when i first got my 4runner, my girlfriend and i went from austin to Big Bend. camped and did the river road out there for 3 days. such an awesome experience. that drive was 8hrs out and 8hrs back, plus the 3 days of "offroading" (there are some soft spots for sure. nothing that the stock 03 4runner couldn't handle easily).
then, we had to move to atlanta so i drove from austin to atlanta, towing a 12' trailer for 14 hrs. not a hickup there.
since living in atl, my girl and i started missing the west, so we packed up again, and drove from atl to moab in 2 days. that was a 25 hr drive. we hung out in moab for xmas and did several trails in my completely stock vehicle. then we drove east to colorado to do some skiing, and got the 4runner tires in some mud and snow. after that, another 20 hr drive back to atlanta
so yea, we've done some road trippin haha. and that's all in the past year of owning this truck. i absolutely adore it. i bought it in march '18 with 143xxx miles on it and now it has 184xxx. the only minor thing that happened was in colorado, it had an episode of hard starting. it sounded like the fuel pump wasn't working, or the fuel rail wasn't pressurized. it would crank, and almost catch, then kinda hang. after doing that 2x, we had another hot chocolate. then i went back, listened to the sound of the fuel pump on start, then it started right up. weirdest thing...
the only non-stock thing is tires. i have nitto terra grapplers in the stock size, and they absolutely kicked ass in the dirt and rocks of moab (aired down to about 22 from 36) and they absolutely ruled in the snowy highways of colorado. being a florida boy, i don't have a lot of exp driving in snow, but these totally covered my ass.
and all this obviously doesn't include the 1.5-3 hr drives for camping and mtn biking excursions. to me those don't really count haha.
