I flat towed a '77 K10 from Randolph, Ks to Bellevue, Ne before. I wouldn't do it again. The only reason I did was because the K10 dropped a lobe on the cam 3/4 of the way to Tuttle creek down there. I couldn't go above 50 or so then the K10 would star bouncing me side to side. The focker's that owned it bitched when we had to pull over for them to get gas in there heep that I was going too slow too. I just laughed and pointed out that I was running double my normal weight and I still had over 1/2 tank of gas.
