question sut vs suv

[NYSUT]

reading this forum since i got my h3 (now traded in for h2 sut), and u guys always seem to be in the know so...
sunday showing a friend my 06 sut (bought new in oct 06) and he points out the rear bumper and asks me if it was hit.
i look and the clearance between the rear bumper and the tailgate/back sheet metal is about 1/2" on the rt side and none on the left.
i figure maybe someone hit me although i am rarely parked anywhere "unsafe".
figure ill wait till i get a chance, go underneath to look for mounts/brackets and straighten it out (i know super anal but truck is new and i am still blacking it out-1 step forward 2 back)
go to work mon look at my bosses 03 suv and it has a closure piece that seals between the bumper and the back of the truck (i figure maybe it has changed since then but whatever).
drive home look at 2 suvs by my house (both 06) and they have the closure piece also.
at this point i figure mine was either never installed or taken off last week when it was serviced, etc.
figure ill order the part today and thats that.
no, see an 05 sut late last night and he has no closure piece either.
actually looks like sh1t compared to the suv back
you shouldn't see push pins on a 50-60k truck? the closure piece looked good.
rambling towards a question or 2:

does the sut not have the same closure piece as the suv (i know the lift gate changes things)?

if it doesn't can i add one on each side (leaving out the middle if i have to)?

thanks for the help in advance,

bill

btw-changed out the grill to black and installed rear tail light guards (see earlier post) and both were pretty quick and easy-thanks
