I have not used a BOB but toured with someone (Dwagonheim)that did.The concerns I hear are a pin tends to break on it (and some have commented on the overall quality of construction)so you want to start with one or two extra pins and that it can cause some swaying that you quickly get use to on steep downhills.I seem to notice that mtn bikes and recumbents often go with the trailers but touring bikes invariable(as far as I have read and observed)tend to stick to panniers.I wonder if touring bikes are less suited to trailers from a handling standpoint .
