My pickup doesn't fit in the garage, so not an issue for me. My wife's car is a Ford Escape, and it's got a 1/4 wave VHF on the top. It hits the garage door. No where near as tall as a suburban, but still, it hits. After doing this for 5 years, I've seen no issues at all with the antenna or the mount. Maybe a slight mark on the inside of the garage door where it hits, but that's it.
I have a Yukon XL (GMC Suburban) ... what 1/4 wave do you have that it has never snapped off? As you point out my truck is talker than then Escape, but I have broken 3 antennas in parking garages over the past year or two.
