Trailer loading? 67/33 trailer axles

I have a question regarding weight distribution on a trailer. The details are not important except that the base weight numbers are fixed, can't be changed. The trailer axles are on a slider and there is three basic load conditions. The trailer in load condition 1 weighs 27K with 13K on the pin and 14K trailer tandems.


Load condition 2 trailer weighs 31K with 18K on trailer tandem and 13K on the pin. Load condition 3 trailer weighs 35K with 21 on the trailer tandem and 14K on the pin.

The 27K weight is trailer and fixed payload, the 4 and 8K loads are limited to the back of the trailer with the only adjustment being sliding the trailer axles. I know this is not an ideal weight distribution but, is it a safe and stable loading situation. There is 2/3rd's of the trailer weigh and mass on the rear and one third on the pin. For a drag along trailer this would be OK for a 48' trailer is that still acceptable?

Thanks,
Steve

 

I know that equal or close is optimal and, tail heavy is not good but, is that worst case loading unsafe or just undesirable? The 8K is directly over the trailer tandems when loaded with no where else to go with it. This is NOT an actual load it is a load scenario, where a 32' container is on the front of the trailer and a 16' container is loaded in the back. The constraint is the truck is a single axle truck with flex-air suspension, 17K max on the drivers.

I don't have any experience with grossly uneven loads, that is why I am asking about this.
