VetteCrazy,
I haven't done it but I've read a few posts of guys that want to try it. Take a look through the Hipo shop forum here.
The tahoe wheelbase looks very close to your suburban. the tire width you may need to accept a lifted look. the underside of the suburban is almost flat cab-front to back. you will need to Fab every bodymount bracket attaching the body to the frame. with luck there maybe a kit designed to fit a Tahoe.
Look at my photobucket below it may give you a idea of what is involved. My sons ME/BS degree takes priorty to our progress, plus he built his
Truck..to check out some of the mods to do to our suburban.
