Our daughter and son-in-law bought our '94 Sub and turned it into a "Pre-Runner" and they still use it for family trips (only three in the family, plus Whisky, the wonder dog).
Diana and I have owned three Subs and if it hadn't been for our having a goose-necked horse trailer to deal with, we would still own one.
We had a custom-built roof rack out of light-weight aircraft aluminum that matched perfectly the roof mounts and those roof mounts were reinforced from underneath with a plate that runs stem-to-stern beneath the factory mounts.
Andy changed out all the suspension, Fabtech I think, and tweaked a bunch of other stuff. He also put a new 350 in it after the original one reached the 200K mark.
I really liked the Suburban for Diana and me. It was never more appreciated than in April 1999 when we were camped on the Baja west coast and one of those sudden spring rainstorms roared in from the Pacific and proceeded to flatten our tent in the middle of the night. We managed to get our sleeping bags, the two of us, and Scooter, the 'not-so-wonderful' dog, in the back of the Sub and have a relatively peaceful sleep. I'm not sure two adults and five--FIVE!!!!:Wow1: --kids would be so peaceful, but they would be 'relative'.
We had the Sub in a bunch of tight spots, including a couple of places in the Anza-Borrego and Death Valley, and when the kids took over the Baja Pin Stripes were permanently etched into the body. It was completely stock except I had switched out the OEM shocks for Rancho 9000s--not the best choice but an improvement over the original stuff.
