I just picked up a used one of these.

It is a bit wide for our 1999 Caravan with the standard roof rack. Research on the web hasn't shown what I was hoping for which would be some sort of extension kit. Do you all know if something like that exists? Second, how much electric motor would you recommend? I was thinking at least 40lb. Not enough?
