Chuck&Gail wrote:Your choice, but 100 feet is WAY long if you plan to run A/C and use non-standard cords. The 30 amp RV extension cords, meant to be used alone at 50 feet, are 10 gauge. If you use TWO of them, and want to use A/C, IMO get an 8 EIGHT gauge cord.
In any case, get a voltmeter and plug it in INSIDE your RV. Watch voltage when you turn on A/C. It will drop, but should come back up in a second to AT LEAST 110 VAC. If voltage is lower, turn off A/C until you buy a bigger gauge (smaller number) extension cord. Voltages below 110 VAC have been known to ruin A/C's.
Totally agree! Especially a problem if campground ALREADY has LOW voltage!

I carry 100' of extension with #12 wire and it works fine. Watch voltage stays 110+ for air and micro. 105+ for everything else.
On edit: If you are stuck on #10 wire get a regular 30 amp RV cord. Many of the 20 amp extra heavy duty cords at Lowes etc have the NEMA 20 amp plug (with 90 degree rotated neutral prong) that will not fit in a standard 15 amp receptacle that the typical house has.

i was told an all 4 of my walk throughs to never run my ac on just the 110 as there aren't enough amps to run i just bought a generator and the adapter cord for that i just figured it was cheaper than replacing a/c unit, now i can go anywhere

Maybe I'm about to learn something here.

The current standard is 120 volts.
Yes, it started at 110 then went to 115 and now is 120.
Many areas the power utilities are supplying higher voltages, closer to 128.
