We have spent approx 8 weeks in our 23TR in the last year and have never given the 30 amp service a thought. We have run everything we have needed to run and never popped a breaker. We use coffee pot, micro wave, toaster, a/c, hot water in the mornings at one time or another.
If I found I couldn't run certain things at the same time I think I would just turn one off for a few minutes. Five campers over the past 42 years and I do not remember ever popping a breaker. Now I jinxed myself,
