I just discovered that although 50 amp service is not normally on the post, for a $20 USD fee they will come out & put a 50 amp receptacle in for you.

I think that all you will be getting is a receptacle. A 50 amp service requires a 4 wire service: 2 hots, neutral and ground. It is actually 2- 50 amp 110 volt lines. Usually #6 wires. A 30 amp service is only 1 hot, neutral and ground. Usually #10 wires. What you would have is no different than using your 30/50 adapter. I cannot see them running A new srevice to your site for that price.

There may be 2 120v lines going to the pedestal.
If there is a 20A duplex outlet as well as the 30-TT outlet, each may have its own "hot" wire. If you add 30A + 20A = 50A.

That was my thought until I put my meter on the 2 hots & had 240VAC. I didn't bring my 50 Amp extension cord as I was unaware of the possibility but the next time we come during the summer I will. I park facing the beach so I have to have nearly 50 feet of cable.

sgip2000: You have started WWW3 with that totally wrong post . I will leave this one to the electricians who will rip that post into pieces. I will add: Please do not ever undertake any wiring projects!

Actually, what he stated MAY be correct-- depends on how "50A" is interpreted.
Could you use a "cheater" to combing a 20 and 30 to give 50 A. Yes, IF (big if) the 20 is not GFI protected.
However, as I suspect most are suggesting, this is NOT the same as 50 A RV service. Correctly they point out that 50A RV service is 50A on EACH of the two hot legs (L1 and L2) for a total of 100A available in the RV.
Hope this clarifies the issue.

And for whatever reason just adding a receptacle can casue some issues in some rigs. (essentially the same as the adapter).
Moisheh when you stayed on my thirty amp site that I had added the 50 amp receptacle to, if I remember correctly you had some issues with your coach. I never remembered to ask you after how that worked out. What was the verdict there.
I added the receptacle for convenience for me just so i didn't have to use the dogbone. The hot is just connected to both sides.

A 50amp plug is just two 120 lines/legs in a single plug. The amperage is determined by the breaker. The problem arises in the coach AC/Heat pumps most of the time. It is all in how your coach is wired and which line/leg of the 50 amp plug is dead. If one side/leg of the 50 amp plug is dead then one of the AC/Heat Pumps will not work. We were in a campground that had a leg go dead and only one of our AC/Heap Pump worked. In this case it was very hot and we needed the other AC unit. I simply started the gen until the repair was made. I have an adapter I bought at Camping World years ago that plugs into two 30 amp hookups or a 30 amp hookup and a standard electrical cord plug in and combines to a 50 amp plug, http://www.campingworld.com/shopping/item/50-amp-rv-box-adapter/25774 The two plugs/lines/legs have to be on different breakers to work. I have used it many times and it works great.

Even in a "patched together" 50 amp outlet (L1 and L2 on the same hot), and certainly in any 30 amp male to 50 amp female adapter, the single hot in the 30 amp is tied to BOTH L1 and L2 in the 50 amp end. So both sides of your RV breaker box should be hot/everything work.
Now, there certainly are monitoring systems that will check for 240 VAC between L1 and L2 and if they don't see it, "assume" that you have just 30 amp service and limit what they will allow you to run.
