I think you need to get off here and on the phone to Forest River and find out why the dimensions are different. :) It certainly sounds like it was manufactured that way, but the question is why. Forrest River may have the answer. I've always assumed that the spacing on axles was equal, but maybe not.
Are the tires the original size? Perhaps larger diameter tires/wheels have been installed at some point. What may have been marginal clearance with OEM tires may be insufficient clearance with aftermarket sizes.
Spacing is within a 1/16 of an inch on both sides. Tires are same size, just LT versus ST.
