Just a that you need to adjust your trailer brakes every three months or 3,000 miles. I'm not sure if the Solitude or Momentum fifth wheels have self adjusting brakes or not. Here's a video from Lippert on how to adjust your brakes:

Since I'm replacing my brakes anyway, I'm putting in self adjusting brakes. For my 337RLS, the price for complete self adjusting brake assemblies was $291.72 (before taxes) from Camping World. This was actually less expensive than replacing the brakes with the original part number from Lippert. And the new brakes are manufactured by a subsidiary of Lippert. If you are considering replacing yours, drop me a PM, and I'll give you the part numbers.

Here's some info on the forward self adjusting brakes:
