After using additional accessories for long time, I realized that I never used them or they were not necessary fir daily/regular driving. I live in south Florida.
I never used the spare tire till I bought new tires. 28,000 miles on the original 32" tires.
So, I took off accessories : gray/black GM Grille Guard
gray/black GM Roof Racks and the Spare Tire
gray/black GM Assist Steps
chrome GM Fuel Door.
chrome GM Grille
Now My H3 has flat rear. I like it. And it's balanced weight matches with new 35" tires.

[:huh:] : Anybody knows the covering kit for "flat rear" ????????? I really really need it.
BTW, I know Japan has covering kit but it is really expensive-$380 for unpainted white cover. I hope I can find it in USA.
