The point you will need to measure from in order to determine the correct placement of a trailer axle will be from the end of the coupler on the trailer. I have attached our "Where to Position the Trailer Axle?" help article for you. Based on my calculation and your information, I found that the center point between the two axles to the end of the tongue will need to be around 127.5". This would mean the axles need to be moved backward around 6".
