As Tom says, relocating the mount is easy to do and will solve your problem in that regard.
When mine failed, I tried buying from Norton but they said it was proprietary to Newmar and so I bought one from them. Expensive....
When mine failed the gearbox actually came apart by pulling the screws out of the housing. My guess is it was underrated for the weight.
Anyway, I was missing the small sun gear because I think the OP tried to fix it and lost the gear. So when I installed the new one, I fabricated a bracket to strengthen the housing. After 6+ years it's still works fine.
You may want to consider something like this for yours depending on the weight rating of the new one.
