Hey there, my family and I are going up to the mountains in a week or so (around 4000-6000ft in elevation) with many windy hills etc etc, and was wondering if it would be ok to take my father's totally stock KZJ78 Prado with a 5spd up there WITHOUT an EGT gauge. I took my BJ75 up there this past summer and it was an absolute dog, like I couldn't get out of 1st on some inclines so we would prefer to take the Prado over that but don't want to cause any engine damage. However, if taking that 1KZ-TE up there without an EGT gauge is truly a horrible idea I'll deal with the middle fingers being thrown at me left and right up there haha. Any advice or opinions are appreciated!
