So I just bought an Rjays Explorer Expandable Rack Bag ready to be strapped onto my luggage rack. Only thing is, they didn't come with tie downs & all I have are some Grunt ratchet straps (which are strong enough to secure a car). If anyone can give me some ideas on how you properly secure your tail bag & prevent it from falling off, that'd be great. Also, posting pictures of your secured tail bag will be very useful. Fire away!
