Smitty,
As one who as always liked to leave things as the original designer meant them to be, I really appreciate a nice looking stock car or truck that has been shown proper respect.
Like so many of the others have said, this is your slice of pie, so anything you choose to do to it is up to you.
However, the fact you have a GMC Suburban in the great shape it appears to be in is remarkable. You can always save the rodding stuff for it down the road. My advice to you is that you tread lightly and slowly, and when making changes, try and do them so they can be reversed later down the road if at all possible.
Whatever you decide, most of all enjoy your old work of art, as many folks just never will!
