Telerik Tab/MultiPage Page Size Results

I have two pages with RadTabStrip/RadMultiPage controls. Both the multi pages having the RenderSelectedPageOnly="true" setting. Both pages share the same user control, which has the same data. The interesting issue I'm having is that the first page is around 300K, whereas the second page is around 80K. I'm not sure how to figure this out because the control present has the same data, the same controls present, and the pages are identical. I verified both pages has RenderSelectedPageOnly on.

Any ideas where to look first?

Thanks.
