ok people here are the ramps ive made there is an easy way and a hard way
the pic with red i put a block of wood there so the screws didnt go up threw the ramp if you look you will under stand the one with the handle is the harder on and the one with the crate is the ezy way lol the one wit the red has a door hing so it is adjustable and you can go both ways its up to all of ya for what ramps you like
