Yeah, as Jay says, they are really good. It is better now that I have sunk it in the ground as it doesn't get in the way when not in use but it wouldn't be a deal breaker and you COULD add a pit but I didn't see the need

I have a roller trolley and a seat on wheels that you can move up and down and I find it really comfortable and useful.

the ramp only blocks the sills and if you wanted to access those you can just add more rubber protectors to lift it clear. You can move them too as they have wheels that slip under.
