Can you fit an Omnistep to front cab of motorhome

We are in the process of purchasing a Bessecar Motorhome, while I can access the van form the habitiation door without using a step, this is not always going to be convenient, as we will be travelling with our 2 dogs.  I find the height of the cab to be quite high and difficult to access without having a step to get in, as my replacement knee restricts me. I am hoping to be able to take the van away on my own with my dogs so therefore a permanent step, such as an electric omnistep would be useful.  Any help or suggestions with this matter would be greatly appreciated.

Thank you in anticipation,

Debbie
