Now I'm a little concerned. The Escape presumably has the usual 30-amp capacity power cord, and the extension cord shown is the common 15-amp capacity variety. If you plug into a 30-amp outlet with the extension (and an adapter on each end) you need to understand that your cord capacity is now only 15 amps, and yet there is no circuit breaker protecting you from pulling up to 30 amps through it. Just start the air conditioner (if you have one) and you have probably overloaded that extension cord.
Sometimes a 15-amp extension is used to plug into a 15-amp outlet - there's no issue doing that, and it is commonly done when the trailer is parked at home (rather than actually camping). The situation is similar if a campsite only provides a 15-amp outlet: you are limited in what electrical devices you can operate, but at least the campsite's circuit breaker should protect your extension cord from overloading.
