Bought for my WhiteHawk which has a wide range of axles. I bought these thinking they were as good as the B&L set I bought for my old camper. The steel is thinner and all the joints are large rivets of the type you use a rivet gun on. The only positive thing I see is the price (not much cheaper than the B&L set my dad bought for his Whitehawk and they came with a set of (very cheap) locks. All in all I would probably do it if I had to do it again Buy a B&L, my old kit used bolts to mount heavier steel parts.
