This is just me but the only way I would use one of those orange WALMART extension cords would be to run thru the open door of the trailer and plug in one item at a time...
You may want to purchase a good 12-gauge (12-3) or even better yet a contractor grade 10-gauge (10-3) 50-foot extension cord... Then you can use your adapters and plug in the RV UNIT using its shore power cable...
I found a couple of the 50-foot 10 Gauge extension cords at a yard sale...
The RV places use them to hook up all of their RV units on display... You might be able to make a good deal with them. Especially from the RV DEALER where you got your RV from... I had them throw in a couple of their used 25-foot long HD extension cords when I purchased my unit.... That was sort of a funny thing - After I had made the point I would like to have a couple of them the sales lady said I'll be right back and pointed at a couple of the cords laying on the ground not hooked up... I didn't catch on what she was meaning so she came back and noticed I didn't load them into the trailer so she said it all over again and left for a few minutes... I loaded them puppies right up haha....
Another thing I will not do is use one of the small round RV ADAPTERS... All of mine are the long DOGBONE type RV Adapters.
What will happen using the smaller low amp type extension cords is you will burn up the adapters or even worse burn up your Shore Power Cable connector... Not worth it for me to short change myself...
You could also burn up some important items like the Air Conditioner or high wattage microwave by trying to use them from a weak extension cord and have alot of voltage drop...
