Another option would be to go propane for more cooking capability. We have a single burner similar to the photo. We use it a LOT. Heats things up quickly and does big pots (like for corn for ex.). There are two burner ones as well and many styles and brands. We plug ours into the quick-connect under the TT. I made a dual quick-connect setup so I can run the Weber Q and cooktop at the same time. No need to ever worry about voltage drop and under-performing appliances either. Depending on where you go, 50 amp pedestals can be hard to find.
Technically, the #10 shore power cord itself is not protected downstream from the adapter. You'd definitely not be permitted to do this in building construction. But people use a single 50-30 amp adapter on 30 amp RVs all the time. You simply can't draw more than 30 amps due to the 30 amp breaker in the panel inside an RV. Not sure I'd trust something called a Mighty cord esp. if it happens to be made in Ch*na and doesn't have UL/CSA
