Have a frontrunner rack on my 16 rubicon and an arb 2000. No, I do not leave it on all the time for the following reasons - I think it looks silly, it's loud when driving, too many meth/pill heads in Nc would try to steal it then fail then get frustrated and damage it, I'm sure it hurts mpg's but I drive two jeeps, a trd 4runner, and an ss camaro so that's not really an issue. The biggest issue is it literally takes 15, maybe 20 min by myself to put it on. I leave the FR awning brackets on the rack all the time so i just lift an end up, throw a nut on scoot down to the next bracket throw a nut on etc. That's just me.
