Propane oven verses drawers
I would like to comment that we have a propane oven and we use it often.
Now we have a microwave and not a convection oven. However you do need to be on shore power to run a convection oven, propane oven works when your not plugged in. The other issue is when you don't have a 50 amp hookup. We've had to live with only a supposed 30 amp feed that I don't think will even give us 30amps !
We have to juggle what appliances, air conditioners (we have 2), whether our hot water tank is on hydro or propane ! We can't run both air so we turn the living room main off and run the bedroom air overnight. The bedroom air we had it installed later and did not want it to feed the ceiling ducts and it has it's own controls. Usually we run our hot water tank on propane to run air and fridge etc. we have to shut the air off to make toast ! So the same would apply for a convection oven!
So as a previous member said you can put stuff in the oven when your not using it ! But if you don't have a 50 amp which is 2 legs of 50 amp for a 100 amps total with the propane oven you can cook in it and still run your main air conditioner ! You do run the oven exhaust fan but you really don't want to turn the air off to run a convection oven !
