Wow...thanks everyone for the great ideas....looks like I have lots to think about as well as lots of options. I'm glad to know there are others who have found a work-around. I get to benefit from others' brainstorming/trial and error.
The real question, however.....and it boggles my mind....is why they still design RVs with electrical components that cannot be supported simultaneously by even 50amp service (let alone 30amp)...with all the technological advances in the world, you'd think they could figure this out......and I don't expect an answer, mind you..this was purely rhetorical....; ).....this question ranks right up there with why RV manufacturers still build coaches with decals....sigh.
Thanks again everyone for all your help!
