Hi guys, I'm in need of 50 ft of 110 shore power and was wondering if 10 gauge would work ok

Not enough information provided.

The answer depends on how much current you'll be drawing---inductive loads may draw sizable startup current---and how low a voltage your loads are willing to tolerate.

Keep in mind the park/pedestal wiring may also contribute to the voltage drop under load.

For 50' length, you'll be fine with 10 gauge for 30A service. At 100' you would need to drop down a gauge(bigger wire). I have many marine customers running 2 25' power cords for 30A with no issues.

Thanks for the replies
I'm running 30 amp, dedicated breaker from my shop to my TT. My concern was if 10 gauge was enough to keep everything going while I live in it without blowing a breaker.
Sorry if my original post wasn't too clear
I'm new to this and living in a trailer

I installed a dedicated 30 Amp service from one end of our house to the other side of the garage this summer. The total run was 87 feet. Per local code, I had to use 6 gage romex. You may be able to get away with 10 gage or if longer than 50 ft, 8 gage, but I'd suggest you contact the building inspector for electrical installations in your region and get their take on it before buying any romex. Better to know you comply with local code than to install it and have to redo it or worse, have an incident and have your insurance refuse to pay for damages.....

When I was doing mine, I thought the building inspector was out of his mind saying I needed 6 gage romex. I went to Home Depot and looked up the 30 amp service requirements for a 100' run and was suprised to find 6 gage recommended.

Here's one source of how to do it: http://www.myrv.us/Imgs/PDF/30-amp%20Service.pdf

Last week I was was at a cg that had power issues at my post so I had to run 50' 10 gauge pigtailed from my 30 foot 50 amp rv cord to the next site.
I was getting 117v at the post and 108 volt in one of my trailers outlets (with nothing but 12 volt lights and fridge running). This shows what kind of voltage drop I experienced with 75' run of cord. 108 volts would not be enough juice to run the ac (thankfully didn't need it) and I had a heck of a time making toast in the morning.

So if I just run 110 to the trailer do I need 30 amp service? I'm kind of confused as I just had the walk through with the tech and he told me that I can't run the air on 110 and that I need 50 amp?
The shop is 50 ft from the house, the shop is 110, my trailer will be 50 ft from the shop.
I'm thinking that there's not enough power.
What do you guys think?
I want to live in the trailer and have the fridge and hot water and lights.

If you are going to run much more than lights you will need at least 30 amp service. If you have two a/c's or want to run an a/c and say the microwave or if you have an electric fireplace or a space heater you will probably need 50 amp if you want to run anything else at the same time.

Take the time and spend the money to do this right the first time, it'll end up costing you a lot less in the long run.

Fridge, hot water and lights all on electric will tax 30 amp service if you try to use the microwave or a hairdryer at the same time as the others are on.

I looked at all the power cords at the rv parts place and a top of the line cord is only $100.00 compared to a cheap one at $50.00.
Money is never an object to me when it comes to doing things right
Like I always tell my employees cut once, not twice because it costs me more money
