The popular replacement macerator hose on Roadtreks is the Sanicon hose. Likely it will fit the ERA also. This hose is very flexible and easier to store - at least compared to the OEM Roadtrek hose. I have not replaced mine yet, but it is a matter of getting under to the macerator and being able to get the hose from there through the brackets to where it is stored and used. Connections seem to be the easy part - logistics are the difficult part. The ERA may be easier than the Roadtrek. An RV service shop will do it if you don't want to attempt to do it yourself.
