I do it here all the time here with our 13,500 BTU Air Conditioner on a separate 20AMP circuit from my garage.
My POPUP Trailer is a good 50-feet away from the garage in the back yard and I use a 50-foot 10-3 HD Extension cord and a RV30A-15A 'LONG Dogbone' type adapter from WALMART...
The 10-3 contractor type HD Extension cords are expensive but I was able to find a couple for sale at a yard sale. You might be able to talk a local RV DEALERSHIP out of a couple of used long extension cords for a good price... When I bought my trailer they passed-on one to me for the asking... These were M/F RV30A cables.
We always watch what else is on in the trailer and don't have any problems getting any connections hot outside or tripping any breakers in the garage...

Do you think I'd be OK using the 15 amp circuit?
