Sorry, not quite. It drops one of the 50 amp legs from the circuit, and passes the other 50 amp leg to the TT. The dogbone would certainly allow all 50 amps of the leg from the pedestal to enter the RV, if there were sufficient loads turned on, and the dogbone would certainly be overloaded in such a case because the dogbone does nothing to limit the current. Fortunately the main breaker of the RV will prevent disaster from happening, because it will still trip at 30 amps and prevent the dogbone or shore cord from being overloaded.
Maybe I'm being pedantic, but there is a difference. A proper 50 amp campground plug is two 50 amp legs, NOT a 30 amp and 20 amp leg, which is a common misconception.
But you are correct with the part that counts: use an adapter to plug a 30 amp RV into a 50 amp pedestal, and the RV still effectively only has 30 amps to work with.

Jerry; I apologize for the sarcasm. I was getting a little frustrated with all the miss-information that was being given.

Quote:what laws are broken if you do some rewiring of a RV?
bumpy You never violate the law by doing wiring, you might violate a city code or an ordnance but never is it against the law. Now that's not to say you couldn't be charged for negligence but that's a whole other thread!

I don't think it was really miss information but rather 2 different 'tings were being discussed- both correct.
You stated:
"A 30amp service cord will not plug into a 50amp recepticle. If your TT has a 30amp electrical panel it would have to be replaced with a 50amp. That could be costly but doable. About the only problem you should have is running the ac and microwave at the same time. "
Which is correct but Rj grabbed the first line and assumed that you meant that there is NO Way for a 30amp to fit into a 50amp- but we all agree a Dogbone allows for the 30/50 connection.
..and I'm pretty sure Rj knows that a 30amp Rig is limited to 30amps even when plugged in to a 50amp receptacle
Now let's talk about negligence- 5 pages? 10 pages? nyuck nyuck nyuck

UPDATE:
We actually got the 1996 Kit Companion Road Ranger 28ET for $3k, quite a solid deal for the age and functionality. You try and find a comparable age/price/size on Craigslist-from a DEALER/REPAIR shop even. Most folks seem to be unable to hook them up and show them off properly, but not at the dealers, they were super proffesional and went over everything.
THey are even going to haul it out to our RV Park(BigValleyWoods-AWESOME park!) near Sandy, OR, for just $125. Lower it, make sure it's stable, hook it up to systems, go over a few things etc. Then later on we can do the more solid cinderblock/wood foundation.
Now the biggest issue is moving/selling things from our apt, buying must haves for the trailer(like a $100-200 surge protector for the 110v cord), as well as insurance and DMV related things, like tags(for insurance etc).

Just for comparison..
I live in my 1995 Prowler 30.5 foot 5th wheel full time all year around.. 24/7/365.. hot summers and freezing winters..
The prowler only has a 30 amp 110 volt power system.. that splits up at the power panel and provides ...
a separate 110v circuit down each side of the RV...
a separate circuit for the Microwave
a separate circuit for the Air Conditioner
a separate circuit for the converter and all 12 volt systems
a separate circuit for water heater element
At any given time, day or night, there are several things running at the same time..
These four things are always on 24/7
** Dometic refrigerator only runs on 110v AC.. not gas
** 110v AC 5 cu foot upright freezer
** 110v AC heating element in the water heater
** 110v heat tape on water hose
** 110v to feed the 12 volt converter and system
These things are usually on about 18 to 20 hours every day AND at same time as the above things are also on..
** two desktop computers
** a HP all-in-one color printer..
** a cyber-power 825 AVR surge protector/monitor system
** 27" color television
** a 110v two tube 48" Fluorescent ceiling light
and these things are turned on as needed ..
(NOT all at the same time or course)..
** 13" color television
** 110v AC mattress heating pad
** one 110v 18" fluorescent light fixture over bed
** two 110v incandescent 100 watt bulb lamps
** two 110v incandescent 40 watt bulb lamps
** a small 110v bathroom heater
** two window fans
** one box fan
** 3 VHS/DVD player/recorders
** 110v rooftop air conditioner
** 110v Toaster Oven
** 110v 12" electric fry pan
** 110v Mr. Coffee
** 110v Tea Pot.. heats hot water for tea and cocoa
** 110v Vacuum Cleaner
It took a couple of months of experimenting with different setups, but now I don't worry about tripping a breaker because of too many things being on at the same time.
Although I have had the the GFI trip due to heavy rain or snow, because the outside receptacle is on the GFI circuit..
and of course common sense comes into play.. for example the coffee pot is on a different circuit than the toaster oven .. etc...
So simply experiment with your RV and find out what works for you..
Best Wishes,

TWO CENTS WORTH
The story goes that a man died and was approached by the Devil who told him that he could buy his soul back for a dollar. The man searched his pockets and could only come up with 98 cent. While begging the Devil to forget the two cent he was short, an Angel happened by and hearing the Devil laughing, asked the man, "Would you mind if I put in my two cents ?" The Devil got so mad that he exploded in a puff of smoke and the man's soul was saved.
The moral: Sometimes putting in your two cents worth makes a difference.
