I have seen that set-up before. I guess you can use the outside step for placement but I would not like it. I think I would check the GVR of your trailer. Does it have the 10" wheels?. You might be stretching things here for a 23'. You might be able to score a used bigger trailer for less ching your thinking of investing to get her road ready?
Anyone else agree?
