Let's see: I don't want to use a jack rated at 3500 pounds to lift 3000 pounds because it might put too much stress on it, but I'll tow a 7000 pound trailer with a 900 pound tongue weight with my truck that's rated to tow 7500 pounds with a maximum tongue weight rating on the hitch of 1000 pounds, and freely state that it's designed to tow that much, so no problem ???
Seems to me that's displaced concern for a $200 jack while no concern about a $45,000 truck ????
My DW has a "favorite carving knife" that she never uses, not even at Thanksgiving.... "I don't want it to get dull" is the reason.....
