Trailer capacity
When I got my trailer the instructions were not to exceed 45 lbs. Has this changed? I read recently in Nashbar's description of the trailer that they had made the swing arms bigger and that they could be retrofitted to older trailers. Regarding BOB capacity of 70 lbs, I don't see how this kind of weight could not affect the handling of the bike, looks like the same physics are in play for all one wheel trailers. There is currently a guy on tour(Victor Weinreiber, crazyguyonabike) with a heavily loaded BOB that has had 2 failures of the swing arms.
Happy trailering
