Has anyone got experience putting a roof top tent on their standard Safety Devices roof rack? I have the opportunity to get one (the rack) close by and while I really want to go get it - I am a little unsure if the tents they make these days will even fit on one. Bottom is not even for one - and the side rails might be in the way? Anyone tried this? Might require one of the more expensive pop ups that don't fold out. Thanks!
