No major problems (yet). Mine has the small v8 with tow package so it is slow going up hills with a trailer. At 100k miles transmission is starting to have rough shifts when cold. Haven't done much towing or city driving and it has a cooler as part of the tow package. Original Goodyear tires lasted 92k miles! Still on original disk brake pads at 108k miles. Best truck I have owned.
