Wife, wants to take our 42' MH to sisters home for a visit. Wants to use extension cord to simply run refrigerator keeping food safe. Otherwise we do our necessaries in the sisters home.

Really !! Can this be done?? How???

Yes. Not even a big deal. Although I do recommend a cord with #12 wire. Up to 100' is fine.

Make sure the water heater is off or set to propane. Use all the lights you need.

If everything in the RV is up to snuff, there's no reason why a GFCI outlet shouldn't work fine, in the vast majority of cases at least. Most times when an RV trips a GFCI it's due to an actual problem somewhere: a neutral/ground short, or a leaky heating element in the fridge or water heater, or what have you.

(You need hundreds of feet of wiring for capacitive coupling to become sufficient to trip a GFCI, or maybe a dozen or so electronic devices with three prong plugs and RFI filters.)

As a master electrician Ii did side by side testing on my 2 trailers. It has also been verified by many others on different forums. Lots of times 2 GFI outlets in series do not play nice. Neither of my trailers would work on with 2 GFI's in series. Either turn off the RV gfi circuit or plug into a non gfi outlet and everything was fine.

As enblethen said, this is very do-able, but with a warning.

Set up the 6-15 to 14-50 (wall plug to RV) adapter and then go into your AC distribution panel and open the breakers for everything you don't need to leave powered up. That will be at least:
Power to all A/Cs
Power to the water heater
Galley power (Microwave, coffer maker and what all) If you can't separate these, PLUG THE plugs.

Be sure to leave power to the reefer and the converter.

It is almost a given that someone will try to use something that will pop that breaker if you leave power available.

You need to purchase a 12 ga heavy duty extension cord. Also purchase a 15/30 dog bone. Amazon is your friend. You need to plug into a NON-GFI'ed circuit.

yes If you have a 50 amp rig. You need a 15/50 or a 30/50 + 15/30

It should be as simple as an extension cord plugged into an outlet in the house. At the RV end use a 15 amp to 30 amp adapter. If you have a 50 amp rig plug a 50 to 30 amp adapter in.

Turn off the AC.

Somewhat easy to do!
I am guessing you have a 50 amp detachable. If not I will revise what I show.
Big question is how far are you having to run cord?
A fifty amp twist lock to 15 amp Adapter
Now the cord minimum #12
This would keep your big cord in rig!
Non-detachable cord would use adapter Adapter
