Picked up my very first M720 yesterday. Drove from Spokane to Tacoma WA to pick-up. Based on testimony here, I brought ratcheting cargo straps with me to fix the draw-bar in place. Once we had the draw bar in place, we found the left wheel was toed out. The tie-rod was bent, so we adjusted the tie-rod until both the left and the right front wheels were parallel with the rear.
She towed home like dream with the draw-bar fixed in place with the cargo straps. All the way at posted freeway speeds. This was with a 1994 Ford F250 Powerstroke.
I would recommend, to the moderators, they post this method to the -top- of this thread, it might save some folks a lot of time. My apologies, I meant to take photos before I unhooked it all but forgot. It's very basic though. Two cargo straps from the loop under the draw bar where the safety chains go through, to the loop welded to the front frame near the tire. One on each side. Ratchet the strap until the front wheels are parallel with the rear and make them -tight-. Secondarily, check the toe of the front wheels. I'd recommend if anything, they need a slight toe-in, but anything as close to parallel should work well.
That's my story.
