I queried Jayco on why only the Whitehawks have these wider spaced axles. The reply from Judy at Jayco was:
"The Whitehawk has our "Tracker Axles" feature. Wider axles distribute the weight of the trailer more evenly, and provide a more smooth towing experience."
She did not address the issue of why other lines do not have these wide spaced axles, as I had asked for. Oh well, I tried.
