Rookie RVer [emoticon] here!

Are there any benefits to plugging my 30amp (using an adapter of course) into a 50amp? When I have the option at campgrounds to plugging into either 30amp or 50amp I’ve been purposely plugging into 50amp with the belief it’s more stable.

not sure what you mean by 'stable'. when we had a 30-amp MH we would occasionally plug into the 50-amp hookup when/if the 30-amp receptacle had visible damage, was loose in the box, etc. IMO beyond that there is no practical difference. we have run into a small number of parks that forbid the practice of plugging into the 50-amp with an adapter. I'm sure there is a reason for that but I've never heard it.

Agree with rk911, the only real advantage is the 50a plug is usually in better shape. Another possible advantage would be if the 30a feed had a lower voltage level but you might not be able to get the other leg on the 50a with your adapter, so it would be a moot point

I used to do it only because the 30A outlets were often worn out and loose.

Many times the 50 amp is less worn…tighter.

Depends on many things. If the 30 amp outlet is in top condition. And the box is a 20/30/50.. Likely no other than if you draw 32 amps you won't have to go outside in the rain to reset it (just reset the main indoors)

If the 30 amp outlet is not all that good. Then likely yes. and often the 30 amp is not all that good.

And in one case the TT-30 plug on the trailer was... Short bladed.. did not make contact with the outlet.. Grabbed my 30-50 and the poor RVer had power at last.. he later got his own adapter and returned mine.

A good idea is to be adaptable to anything.

Short answer, no. Many longer posts shown above but none of them will get you better service than a good working 30 amp plug.

Obviously if the 30amp outlet is in bad shape or there is a big difference in voltage, it's probably safer to use a good condition 50amp outlet with adapter.

But if both appear to be in good shape, there is a minor issue in that the circuit won't be protected by a 30 amp breaker. If you limit yourself to the continuous 24amp rating (note 30amp is a peak load, you only get 80% for continuous), it should be fine but if you get silly and try drawing 35-40amps, you will be overloading parts of your electrical system but the breaker on the pedestal won't trip.

The 30A breaker in the RV provides the protection.
