Mounting Generator

Yes, I have the generator and it has very little time on it. I cannot see how adding weight on the back doubles the axle weight. Will look into it. Thanks

It's really simple if you consider that ALL the weight of the 5th wheel is carried one of two places - either as pin weight or on the axles. Therefore, just as an example, if I start with a 5th wheel that weighs 14,000 lbs total with 20% of that as pin weight, then I have 2,800 lbs pin weight and (14,000 - 2,800 =) 11,200 lbs on the axles.

Now, if I add 500 lbs to the rear of the 5th wheel and, because of the teeter-totter effect (actually, forces and moments) unload the pin weight by 200 lbs, then the total weight of the 5th wheel is 14,000 + the 500 lbs I added = 14,500 lbs, right?

However, I removed 200 lbs of pin weight, so my new pin weight is 2,800 - 200 = 2,600 lbs. If I subtract the new 2,600 lbs pin weight from the new 14,500 lbs total weight, then I have 11,900 lbs that can only be carried on the axles, so my axle weight went up by 11,900 - 11,200 = 700 lbs by adding 500 lbs to the rear of the 5th wheel.
