There's a few reasons I don't want to build my own.... first is making the expanding clamp for the hitch to prevent sway is a PITA.... so its a bit more than just throwing a 2" receiver and hitch pin in there. Second, I often have 2 bikes on there (4 on a rare event) and the cheapest of those bikes has almost $2k into it, so a solid/proven carrier is worth the investment IMO. I can't stand when I see someone with a $4000+ carbon bike bungee corded to the back of a Honda civic (seen it)... spend $40 and get a trunk mount damnit!

So yeah, there's certain things ill draw the limit on fab'ing.. a bike rack is one of then. Hell look how much time I put into roof rack mounts..... lol I don't want to put the design time into a bike rack to get it up to MY standards; there's products out there I can buy already that I like.
