Having towed a 19' Bambi and a 25' Safari as well as when we were kids having seen what a 24' SOB towed like, I offer the following info:
24' SOB (dual axle) with all the proper hitch and sway. It towed just fine (towed a least 20,000 miles).
25' Safari w/ dual cam system (dual axle)-- tows perfect (but only about 50 miles so far).
19' Bambi (single axle) with friction sway and weight bars, no sway, no bounce, no nothing. Towed like a dream (having towed it about 1500
The SOB was towed with a 77 Ford LTD wagon with a 400ci engine and then a 1985 Suburban 2500 w/454. The Bambi and the Safari were/are being pulled currently by a 1996 Impala SS 350ci LT1.
