2000 Georgie Boy Landau Ladder Needed

We own a 2000 Landau Georgie Boy Motorhome and while we were trying to park it we backed into a tractor snowblower in the shed, well now we need a new ladder on the back and the universal ladders are to short and they seem really thin compared to the original one. Does anyone know where or who we can talk to, to purchase a new ladder for our motorhome? The one on there now measures about 8'10" from the top of the arch to the bottom, it is 12 1/2" wide with 7 steps, the steps are 14 1/2" apart and there are two braces on the ladder attaching it to the motorhome inbetween the top bracket and the bottom bracket. Any help would be greatly appreciated.
Thank You,
