Welcome Walter ~
The situation you're describing can occur with ANY RV (any brand, any manufacturer) which has 30 amp service.
Simply put, it's usually the result of using too many electrical items at the same time. I guess you could
say it's another *sign of the times*..... RV owners now want all of the comforts of home: air conditioning,
electric hot water heater & electric refrig, microwave, multiple TV's, coffee pot, computer, cell phones,
etc, etc, and a 30 amp service can't run all of these items at the same time!
It takes a bit of strategy
(especially when using A/C), but as others have you said, you'll learn
to vary the use of electric appliances & gadgets whenever necessary.
Your Keystone owners manual will have a list of 'amps used', and you can also read some info here:
Hope this helps.
