buzz,
Do you have any idea how much total weight was involved with this Max Load? It would be nice to know where the edges are. I don't have a pic, as I was totally involved in getting my rig from A to B without incident, but, our Max load was 8 yrs. ago when we had the truck, Lance, car trailer with a 4400 pound jeep on there and a whole garage full of heavy metal stuff (like tools, transmissions and floor jax). My estimate of the Combined Vehicle Weight was 18K pounds on a truck whose CVWR was 19.300 pounds. I did not weigh this load, just tried to get it to B without blowing a tire or something going haywire. There certainly is a heightened sense of awareness. My gut tells me you were at or over that higher figure. It does move one to pay attention to every noise and possible visual menace.
regards, as always, jefe
