you to post their RGAWR's...but you might be right...I just didn't
want to spend the time to weed through several dozen F150's
checking if they have a tow package...
Looking at Fleet Ford body spec sheets shows 7 different RAWR from 2012 up to 2015 at 3300/3500/3800/3850/4050/4550 and the biggest at 4800. Which GVWR packages they go with I have no idea.
IMO the OP has got his answer and its quite obvious from Fleet Fords body service spec
Fleet Ford on the F150 and the F250 they are two different vehicles. Even the F150 HD is simply out classed by the F250 HD for pulling/or carrying heavy loads.
