Source for a new ladder for a Lance

Anyone have a good source for a new ladder for my lance 1010? It has a topline ladder on it now, one of the shiny aluminum ladders I need to replace it as it was destroyed in superstorm sandy last fall. Ive replaced/repaired all the other damage from the storm (tree fell on the camper) this is the last repair.

I talked to Lance yesterday but the shipping cost was crazy expensive. So im looking for another option.

I think the ladder is the 501l on the topline site is that correct? Ive not gotten a call back from them yet.

any thoghts or suggestions are always welcome.
