My 99 2500 has 212K on it and atleast 50% with trailer on it (not real heavy though), 3 lift pumps and 1 VP 44 inj pump (caused by first bad lift pump and no pfuel pressure gage) Has had pressure gage since VP failure , which is abloulte necessity, NOw you can see the lift pumps apporach failure and change them!
Had the NV4500 speed fail due to a Lube failure at 202k miles. (wrong lube installed by me at 125k miles, bad on me and costly also.
Truck still runs better than new and will upll my trailers down the road and in the mountains for years to come even though the body may fall off in piles of rust and I live in Wyoming at 19% average humidity and minor salt on the roads that I travel. OH WELL!!
