Our truck....don't use anything usually. Will drag the ramps out sometimes, esp. if it's nasty outside and I want more room underneath.
Other than that, anytime the truck's in the air, it's on stands.
BTW.....the ramps I have include a flat pad that attaches to the end, allowing the vehicle to sort of pin the ramp in place before actually rolling up the incline.....so no ramp scooting out of place. But I do prefer jack stands for any real work on a vehicle....just a pain to get the floor jack out, stands out, position both, etc., etc., when all I want to do is change the oil.
