Actually, the "short answer" is, using the 50 amp dogbone adapter isn't likely to hurt, and very well MIGHT help, in most situations...

Got me to thinking, why not just use 50 amp service whenever it's available? I would be assured better quality power, and everything in my MH is protected with breakers, so, why not?

Anyone have any ideas on why I shouldn't do this?
The 30 amp breaker at a campground many times trips during brown outs or because it just has aged to the point that it is no longer capable of handling a 30 amp load. In these situations I will use the 50 to 30 dog bone to plug my 30 amp rig into the 50 amp socket so my autoformer can correct the low voltage situation without tripping the breaker or to overcome a faulty 30 amp camp ground breaker.

This will protect your equipment as you will not be getting additional power loss/voltage drop as the 30 amp breaker starts to fail. You may even notice that while the 30 amp breaker will be running hot along with your power cord everything may start to cool down once you plug into the 50 amp with the dog bone.

The risk is that if you have a short between the 50 amp dogbone and your 30 amp main breaker inside the coach then you could damage your power cord and electrical gear between those two points. If that concerns you you could put an inline 30 amp breaker beween the 50 to 30 amp dog bone to protect your power cord however that would be your call.

For me I know the condition of my power cord along with its connecting plugs and have a 30 amp SurgeGuard in line with a 30 amp AutoFormer to protect me against power faults between the power post and the coach so I am comfortable with doing this.
