You should be thankfull..you have a Power-house.!!
Our 1 Ton Chevy (1951) only had under 19,000 mi on it, Grain/Cattle bed and Single wheels (Slit-Rim)...Top speed, we never exceeded 50mph... 100 Bu of Soybeans up the East side from the river with all the run you could get from the Stop sign would yield 13 MPH at the top of the hill..Still in High gear.. Dropping a gear only meant you went slower... Sure was a steady worker at low RPM...!! If it rained, you had a choice..let the engine work and NOT see, or let up on the throttle and the Wipers would work a little..!! But, the Heater worked good..IF you were lucky enough to be sitting in the middle..!! Be HAPPY..you have a Power-House compared to ours..!!
