Electric cord extension advice...........

Look at your cord it should state what gauge wire you have. I would go one size larger. Price it out by the time you buy wire and fittings you may nor be saving very much. If you build it yourself make sure you use double insulated cord.

Doubt if you can make one cheaper than you can pick one up at WalMart. I just paid $1.40 a foot for 12guage plus ends to make a short cord for another project. $27.00 with ends for 12ft. You need 10/3 which will be more plus the ends. Better to buy a premade with nice molded ends.

Is your rig 30 or 50 ampere?
Rigs normally come with #10 wire for 30 amp and #6 for 50 amp.
Depends on what you are trying to operate.
30 amp with one AC unit, no water heater 120 volt element, you should be able to utilize the #10.
50 amp running two AC units, water heater on LP, you should be able to use the #6.
Building extension cords gets expensive when you start buying the connectors.
30 amp extension cords are cheaper off the shelf at Walmart.
50 amp are expensive no matter which way you go. Easy solution is to reduce load and use a 30 amp extension cord with dogfbone adpater.

Musky50, I am not the real expert here but...

What are you going to run on your 60 feet of wire? If any heavy loads such as AC, microwave, etc. get the heaviest wire you can find, I'd say 10 ga minimum. You'll drop a certain amount of voltage just due to the length of the wire.

Having made a 50 ft, 10 ga cord for my generator at home, I'll bet you can buy a pre-made, molded cord cheaper than you can buy the parts. Unless you maybe have them already.

12 gauge should be good but probably comes in 50 or 100 ft lengths. So get 2 50ft or make your self a 60 ft.

Thanks for the quick response's, didn't think to check just figured it would be cheaper.

Get a 50' 30a RV extension.

50' ft. foot 30 amp RV Century Extension Cord Black $60

Assuming it is a 30AMP cord you need... It should be 10-3 ...

I just looked on AMAZON and they have several listed there less than $100 with molded RV30 amp male-female connectors on them...

Don't short change yourself here by going to a smaller gauge - You will use for this extension cord later on so it should be the same size as what you have (or bigger).

If your dealer is close by go ask them to borrow one for the trip maybe... I asked for an extra one for my house setup when I got my fifth wheel - they gave me two extras.

The dealers are loaded down big time with these cables with their models on display...

I lucked out on this new to me TT. it had an extension cord, pre made type already in it. I know they aren't cheap and from the looks of it, it has not been used yet.

I just hope you have good campground service TO that faraway pedestal. I'm at a state park right now. With all sites not occupied, voltage got down to 102. With A/C running, wife just started the microwave. Dropped to 100. Turned A/C off, went to 108. That's plugged directly into the pedestal. I moved the coach closer today to get away from our 25-ft 10-ga extension. I had gained about 3 volts by moving right to the pedestal.
Complained to the park and maintenance manager came by. Told me our loop of "30A" sites shares one line with a 100A fuse. Says we're getting all he's got to give, amazed the fuse doesn't blow.
