I now have 5 chains left over, they said 6 in use is the minimum you should have, which I have now. The bars are now pretty much level when tensioned & there's tons of room between the end of the bars & trailer frame. The vertical chain angle is just slightly off, but within the angle allowed. They raised the hitch up the shank 2 holes, & added a washer. The TT rides level now & the TV is 1/2" higher in the front & just under 2" lower in the rear then when empty. It handled nicely on the highway too.
