geez i can't believe u didn't grab a creeper and look at the underside...
i thought u were serious about this.
these trucks aren't undercoated.
think about it, the underside is basically OPEN, it's not a unibody thing.
so undercoating would need to be applied WAY UP into every tiny recess,
and ultimately would trap water or salty crud in the worst places.
the fx package will have skid plates under the fuel tank and tranny area, n transfer? case.
the rest of the cab is open underneath.
the bed is painted on the underside with a few bits of sealant in some locations
and a slab of heat shield for the exhaust where it bends UP toward the bed floor.
undercoating a full size truck is problematic.
the fully exposed frame rails are coated.
this used 2b a cosmoline like product but is now more paint/sealant like.
the front wheelwells have a fiber/polymer liner but the rear wheel wells are open (except on the dually).
there are oem and aftermarket liners for the rear wells which work nicely to reduce rock nicks.

the tail gate step is PART of the kingranch package of upgrades.
it can be deleted however.
i was very very against having a tailgate step 4 many reasons and initially worked hard to UNorder it.
however, NOW having used the step for a long time, it's really nice to have and very solid/secure.
btw anyone suggesting there is an issue of closing/sealing a full shell or tonneau on a truck with the step is blowing smoke.
((a common occurrence on dim diesel forums...))
all the major shell makers have adapted the lower rear window/lip to seal perfectly over the step.
as a matter of fact my 6 year old shell which was built for the NON step tail gate fits PERFECTLY.
a.r.e. made available a 40$ lip so that the original rear glass fits/seals perfectly.
as a matter of fact it actually fits/seals BETTER now over the tail gate step than it did on the older style tail gate.
ALL of the newer F trucks (150 and up) have a tail gate lip with a tiny 'dam/aero thing...
so even the NON stepped versions have this lip.
once the rear window/door is closed, one cannot TELL if the trucks gotta a tail gate step or not.
congrats on the new truck!
