Here are some real world numbers. Our 06 was a 3500RL. We had it weighed loaded at one of the the Fall Rallies. It weighed in at 13,775 (11,250 when you remove the pin weight) with a pin weight of 2,525.
For what it's worth, we pulled that trailer out west to Yellowstone and to Alaska with no problems whatsoever with a 3500 SRW. Not trying to influence your decision one way or another. If the numbers you posted are actual, then you will be better off adding the training wheels (duals).
