This is what we do with our OFF-ROAD POPUP trailer.
Since we like to winter camp sometimes or find ourselves up in the mtns somewhere and it freezes overnight we want to use the BLOW-OUT method which takes just a few minutes.
First we drain our the fresh water tank at its low point drain. We open both HOT and COLD water taps at the sink. We also open the high pressure valve for the Hot Water Heater when draining form the low point drain. This will drain a good 90% of the hot water heater contents. We leave the high pressure valve open from there on as well as the low point drain for the fresh water tank. Any small amount of water left in the hot water heater will not do any damage if it freezes up as it has lots of room to expand.
Then we hookup an AIR ADAPTER (AMAZON) to the city water port of the trailer and connect the 12VDC TANKLESS Air Compressor (AMAZON) we have to blow out all of the fresh water lines at the sink taps. All of this water goes down the P-TRAP drain. When we only have air coming out of the sink tabs then we add just a small amount of pink anti-freeze to the P-trap to replace the small amount of water present there.

We also have an outside shower attachment and an indoor Cassette Potty unit and make sure the fresh water associated with those units is drained. We also dispose of any waste water in the cassette potty removable waste tank.
All of this just takes a few minutes an the beautify of this is we can continue using the fresh water tank the next day when it warms up by just closing all of the opened valves and re-filling up the fresh water tank.
We do the same procedure here at the house when we finally leave our POPUP trailer stored for the winter.
This is a little different from your situation but should give some good ideas if you want to go this way winterizing your smaller foot POPUP trailer.
