Buying a Bambi
We bought one Jan 17,2003 and had the same questions. I knew from the forum that I should get a weight distribution hitch and a friction sway control, clip on mirrors, and a electronic brake controller. Your Yukon is prob similar to my Z-71. I couldn't find any lightweight bars for the weight distributing hitch so I ended up with 1000# bars. Also at the time I needed it the available choices for brake controllers was limited, and I ended up with a Drawtite electronic. All the forums have been discussing the merits of the controllers, and I may not have the best set up. However, although that I haven't used it that much, this weekend will be the third time, everything works just great and the trailer is very well behaved with no trace of sway or any other nasty tendencies. The two quick stops that I have made have been just that- quick well controlled stops.
You will love the Bambi, it is perfect for the two of us and our well behaved but still a puppy 6 mon. old Lab.
