I have room for more tongue weight. I can move the tractor another 3 foot forward, I am not really sure if this is a huge problem. But I would have't to agree that typically the axles are further back. Lessons can be learned in a hard way sometimes. If I reach the 10-15% tongue weigh recommended is this really a problem?
Bingo! Thats your problem. I personally have never experienced the sway but I can see where a set up like yours would be prone to wiggle regardless of loading. 60/40 is a more tradition placement for axles. With 50/50 I would think it might actually need more than the 10% to keep sway at bay.My axles are measured exactly in the middle of the trailer. Not including the tongue.
