We went to a CAT scale on Sunday on the way home from weekend camping. I have to say that it was a pretty easy going experience. In the 2 hours or so we were there, nobody else went through the scale. No problems with getting in the way of truckers and their rigs. But they do kinda look at you like you were in Asia and have blond hair....
FWIW, there is really no way you can weigh the right and left trailer axles separately without backing onto the scales, which I don't think would be a good idea.
I had to make 5 passes in total. As I read in several places, the call button really is quite high up. I learned that you cannot step out of your truck and go under the call button to push it or they will weigh you before you get back in. One pass wasted there... You really do need to have a stick to push on the button but it only needs to be about 3' long. Would help to have a knob on the end like a wad of tape.
I had to readjust the angle of the spring bars and number of links twice because at first, the front TV wheels were actually being lifted a bit. That explained why the front end felt a bit loose. Using the initial setup process of measuring the change in height of the front and rear TV wheel arches with a tape measure, that was obviously WAY off. We have a Reese dual cam WDH.
After doing the math, I learned:
The available TV payload is 1,885 lbs. Much lower than the figure of 2,850 that Ford shows. We lose about 250 lbs for the canopy and bed liner. Not sure why Ford's number is so high. I'm pretty sure that their figure includes for the long box, supercab, 4DW and V10 that we have, but I could be wrong.
The trailer weighs 6,560 lbs. The factory UVW is 5,237 lbs. The trailer GVWR is 6,800 lbs. That only leaves 240 lbs of available payload in the trailer. The measured weight seems awfully high considering the stuff we loaded into the trailer would not weigh much. Not very good. We are all loaded up with a "normal" load of food and clothing, some small kitchen appliances and dishes, and a pass-through filled with BBQ, chairs, and hoses and the like. Nothing unusually heavy. And we only have one group 24 battery up front. We have a rear kitchen so there is the weight of the stove, fridge, cabinets, small appliances, food, etc. hanging of the very rear of the unit. We also have electric stab. jacks and tongue jack. Do these weight that much??
Tongue weight works out to 560 lbs. The factory figure is 518 lbs. A problem here is that this works out to 8.5% which is simply too low. The trailer just does not seem to handle right and that could be why right there. There is no way to shift cargo towards the front. The only way to increase tongue weight would be to add lead weights (kidding) on the tongue, but, there is only 240 lbs of available TT payload left. We have a rear kitchen so there is the weight of the stove, fridge, cabinets, small appliances, food, etc. hanging of the very rear of the unit.
We are well under the front and rear GAWR's for the truck and are limited by payload capacity. Presently have about 1,300 lbs of TV payload capacity left, so okay there.
As for weight transfer, I readjusted the WDH by tilting the bars down one "notch". Still lifted the front wheels up. Then tilted the bars down another notch and took away one chain link (leaving 4 loose ones). That unfortunately transferred 160 lbs to the front and 400 lbs to the rear axles and none to the trailer. That's not good so I would have to either adjust the bar one notch or add one chain link. But in view of the low tongue weight, I left it as is at that point and will have to figure out what to do with getting the tongue weight up and then go back.
All in all, it was a very interesting and worthwhile exercise. I think everyone should do this. You might be surprised at the results.
Anyone have any idea how to increase tongue weight without adding overall weight to the TT and without re-arranging payload? I can't see how it's feasible to shift TT payload towards the front that would be of any significant weight. In a quandry.....
Almost forgot, for those venturing to a scale for the first time, may I suggest leaving DW at a shopping mall why the man does all this? I know next time I will! (No comments)
