Hi we have just traded in our three year old Swift Bolero 680FB.
I can honestly say that we loved the MH and hardly had any trouble from it, we kept the upholstery covered as we have two dogs and on the day we took it in, it was almost like new.
We didn't have an electric step so that wasn't an issue.............I don't know if any Boleros do, but I can't recall seeing one.
Ours was a 2007/2008 model and Swift replaced the door, which had known issues.
We didn't intend to change ours and really thought we would be keeing it for a good few years yet, we saw the Burstner that we have now and fell in love with the layout and the fact that it had a garage.
But I would def recommend the Bolero, and just to add that we used ours in all weathers, and even in Winter it was cosy.
