I've been running two heaters on my 30A without any issue. I can even run the microwave when the two are going.
This morning, I decided to vacuum the coach (I must be coming down with something). Only one heater was plugged in, so I decided that I was okay to run the vacuum. Why bother pulling out the manual to see how many amps it draws. It can't possibly run more amps than a microwave and two space heaters combined, right?
I'm just glad that I blew a breaker, not a fuse.
For the record, I use a Black & Decker HV9010P Retriever Pet-Series Cyclonic-Action Corded Dustbuster and Blower
that works very well... and draws 6.25AMPs. Add that to the 12.5A drawn by the space heater we're already at 19, and then add the computer and, waitaminute, we're still nowhere near 30A.Which brings me to the second thing I learned: the outlet above the bed in the backroom and the outlet above the fridge in the kitchen are on the same circuit, which my 19A apparently overloaded. Hence the kablooey.
There's never a dull day when you're RVing.

Your last paragraph tells the tale: although your rig is on a 30A hookup, that power is divided between two circuits inside your coach... so you can only pull a maximum of 15A from each circuit.
As you said, your 6.5A vacuum and your 12.5A heater add up to 19A--less than the 30A available from your shore power connection. However, that's 4A more than you can pull from a 15A outlet circuit, and that's where the problem arose.
And I'll never forget that now! LOL
