sliding loading ramps?
 

Hey all, I found myself a nice project for the time being, although it's not my dream car yet (71 911Targa), next month I'm gonna pick up a beat-up Boxter-S that needs lot of work and need some ramps on my trailer... now I remember seeing once a trailer that had nice sliding ramps but they did not seem to be standard of the factory, anyone knows where to buy a smooth system like that? All I could find now is for example this one http://www.onsaleramps.com/loading-r...-trailer-ramp/ but seems like a non attached thing? Anybody? :confused:
Thanks!
