Toyota hits 30K hours and still going strong

This is a 2004 7FGCU15. The motor and trans have had no work other than a headgasket and valve seals. King pins are still good. I know you won't believe me but the LP regulator is original, but I think that's next on rebuilds. I even think the SAS still works. This unit doesn't have a seat switch or a complex hydraulic control valve. Everything else has had to be replaced or rebuilt. New radiator, brakes, starters, alternator, tilt and lift seals, steer seals, chains, forks, seats, and carriage rollers. I must admit though, it doesn't go over the bumps as smooth and quiet as it used to.

I think L1ftmech is speaking of length of driving, while I think mrfixit, [the OP] was speaking in 'root means squared average miles per hour' driven in relation to number of engine revolutions.
For the equivalence to car's miles, I use a 'root means squared' average speed of 45 miles an hour, so the 30K x 45 gives an equal to having driven about 1 million, 350,000 miles.

"it's not rocket surgery"
There has always been debate about converting hours of use to miles equivalent. Obviously the rate of travel (ground speed) to the hours of use is not a direct ratio.
Some trucks will get more stationary idle time than others, some will be driven faster or slower than others etc.
Most of these trucks (where I work) in this class will be driven at 3 to 4 MPH on average. That is the range I like to use for "shoot from the hip" figuring.
That simplistic equation would yield an answer of around 90,000 to 120,000 miles equivalent.
Typically, the size of the general work space area and distance in which an operator has to work will have a direct effect on the average miles per hour factor one would use in the calculation. Operator personal need/desire for speed is another aspect to consider when trying to decide a hypothetical MPH.

i remember when 10,000 hours was remarkable and usually ready for forklift heaven (the scrapyard) it's amazing how far technology has come. got in this bsns in the early 80's, seen a lot of improvements. still....30,000 is outstanding!!!!

Fact of the week
The origin of "love" as the score zero in tennis is debated, but two main theories prevail. One suggests it's derived from the French word "l'oeuf" (egg) which resembles the shape of the number zero. The other proposes it's related to the Dutch word "lof" meaning "honour" as players might be playing for honour when scoreless.
