I’m full timing and am going to need some heat here in Colorado.
Need some help here please
When did the system last work correctly?
If you put in a gallon or more of fluid *and* the system worked in the past, that's a lot of fluid. Did you purge the air at the various purge points on the system? If not, there still is more work to do. You might want to boost the speed setting on the circulation pump to get it done quicker.
The "big deal" place to look for leaks is by the main system. There's lots of pipe and stuff under there. On a 30' it's under one of the dinette seats. I suspect that's also true on a 33'.
