Heaters at opposite ends of trailer, one on power bar, one on RV outlet. Power bar gives peace of mind because of 1875W capacity & 15A breaker.

To the OP, at the very least, you need a proper gauge extension cord. If you intend to do it regularly, I suggest installing one of these on the side of your trailer.
Use at least 14 ga. wiring to connect it to a single, dedicated receptacle.
It would be even better if you had an inline fuse or breaker so you don't have to rely on the breaker on the power post.
You can get a 15A surge protector power bar but they are a bit pricey.
And most importantly, before you follow my suggestion or that from anyone on the Internet, get an opinion from an electrician.

Some good advice in prior posts. Some are a little unsure themselves. "Most" extension cords are 16 gauge which is only good for 10 amps. A 1500 watt elect heater will draw 12-15 amps. 14 gauge wire is good for 15 amps which is "just barely" adequate. 12 gauge is good for 20 amps which is the correct wire size for the application.
But here's the thing; even a 12 gauge ext cord can cause a real problem if there is any resistance at the plug/socket connections. A small amount of resistance in any (or all) of the connections will introduce voltage drop into the circuit. Voltage drop with a heavy load "like a heater" will create a hot spot in the circuit. This situation might lead to a fire. THIS is why heater manufacturers are adamant about not using ext cords. This is simple ohms law and is a topic I'm very comfortable with. And yes, I have been known to use ext cords with elect heaters, but here is what I do; 1. Choose correct wire size for application, 2. Examine the plugs/sockets carefully for any signs of damage, ( discard or repair if needed). 3. Use some Emory paper or 'fine grit' sandpaper and shine the plug blades, (don't overdo this or you can remove the brass plating which just exacerbates the problem you're trying to fix) 4. Apply a small amount of silicone grease to the blades, 5. Never plug it in and walk off....always monitor these connections for any sign of heat. 6. Never go to sleep with the heater running on ext cords....warm the camper up, then unplug it before going to sleep. Those are things that come to mind. If I think of anything else, I'll make another post.
Good luck

Turbs, that's an excellent and professional looking install. Perfect for a high load device such as a heater or toaster or coffee maker. I may steal a couple of your ideas there.
