What's the best style ramp for loading an atv into a full sized 4x4 pickup truck ?

 

the longer the better

 

Menards has a tri fold ramp made by Fulton (US made). Weight is around 35lbs and they have saftey straps. Price is just under 100lbs. Only down side is they are kinda narrow (will still work with larger 4x4 with oversize tires, but you have to pay attention). I believe they are 6ft long.
