I checked the specs on the same razor and I believe the length was 146" ( that's 12'2")
I had your same problem. I knew the 1000 4 wouldn't fit before I bought it and debated buying a 900 instead but I wanted the 1000.
So this was my fix.
I made he extension 18" long so I have a little extra for bumpers in the future.
It bolts to the back frame so I can remove it if needed.
Does it effect your ride any? Extra weight at the back of the RV equals lighter pin weight as well.

I am assuming that it bolts to where the ramp locks were?
Pretty interesting add-on, give you an A+ for ingenuity.
Looks really good.
