Can't fit as much into a SUV. Like yeah I'll have the topper for the trips to the track or out of state and stuff but I can have the bed space to put stuff in when I move or buy big stuff, etc and can tow as well plus have room for 5 people still. Checked out the 4runner and there's just about as much room as in my car after it's all said and done and you'd have to fold seats down to fit crap, defeats the purpose lol
