I wouldnt change any of my RV Trailer wiring around just to save a couple of bucks... Be safe and just purchase the various adapter cables you need and keep in the RV TOOL BOX. I have my 50A-30A amp situations convered, my 30A-15A situations convered, and even an additional 30A (M-F) 25-foot extension cord situation covered. Never know when the situation comes up and we all know we RV'ers always got to have a PLAN-B or you face the wrath of the Titans. My wife is a full blown Texan and its very true they all shoot first then ask questions as it should be. Somehow I know this first hand haha...
When I pull into a BASS PRO SHOP parking lot for an overnight sleep over and they have 120VAC Receptacles in their RV Parking area I can just safely plug into it and run everything inside my trailer in the 15AMP power down mode..

I'm afraid you are stuck with $80 solution be cause your Rv uses the Marinco shore power setup and these cost more the than the other type. For what it is worth, the 50 amp marinco plugin female to 30 amp male adapter would be my choice as you can now add a small 30A/15A adapter (3$) to run from the house power.
You'll also need a 50A Rv female (not marinco) to 30A male adapter so you can plug in to 30A shore power (you may have one already as they often come with the RV). I also carry a 50' 30A extension cord for when the shore power post is a bit of stretch for the normal 25' cord that comes with the RV.

I ordered a short pigtail which goes from the trailer 50 amp to a standard 20 amp connector (its only about 12" long). I then use a standard extension cord connected to a 20amp circuit in the garage while getting ready to leave or when we come home, and it runs the fridge, tv, heater, and lights for the day or two on either end of a trip, without having to lug out the 50 amp cord. I ordered it from Dyers Rv on the web. Was unable to find it anywhere else, including Camping World.
Just plug in factory cord and then buy the cheaper adptors from wallmart. You can do it all for 30.00 dollars or less. This is what I do. I can carry my twist to lock 50 amp cord and save a ton of money. I think the twist to lock is a nice feature but the fittings are way to expensive.
I would save the $$ and just use propane for the Frig. It does not use the much propane to cool the Frig. I do this most of the time unless I need lights in it for a while.
