Abstract
A ramp is used for loading and unloading recreational vehicles, especially snowmobiles, trucks, trailers and the like. The preferred ramp is a three section ramp with two outer sections and a center section connected to fold from side to side for storage and transport purposes. Each outer ramp section is equipped with a series of rollers spaced along the ramp section to allow the skis of a snowmobile to advance along the ramp without binding. The rollers are preferably made with a rigid core and a rotating outer sleeve of PVC. The tubing is slit helically from end to end so that it can be removed and installed without dismantling the ramp. The center section of the ramp is equipped with lateral cleats.
