Can't say I like 'em much. Mostly, I get annoyed with the folks in the latest Mastadon who think they own the road and want to use sheer size to do whatever they want. And they roll over more than passenger cars, so I'm not too sure about safe. Most folks never hit the dirt with them, so why bother? For my vehicle, I went with a Subaru AWD wagon. Hauls plenty of sheetrock. Mainly, tho: when behind one, I can't see around or through the things (blacked out windows, usually) so there's bad traffic karma; it's better when I'm on my motorcycle, since that's a sportsbike so I can see around/through the SUVs better.
