We've had a
beige Petstep ramp for about 15 years (think we found it at a yard sale). Our dogs don't have problems with trailer steps, but when they are in need of a vet trip or are getting really old, they stop being able to navigate the big leap into the F-250. (It's also useful when we have to transport other people's dogs who have no idea how to do that.) We like the polymer construction because it's tough and won't ding like aluminum. But it's not narrow by any means (I don't think the dogs would use it if it were) and won't leave any steps available for you. You might be able to use it yourselves, as it supports up to 500 lbs, though lawyer-talk in the ad says "animal use only."
