Is this doable or am I overlooking something??

We use our trailer a lot during the winter and in COLD weather.. Normally we use the propane furnace but it gobbles propane. The trailer is connected to the 30 amp outlet on the park post BUT when we try to use an electric space heater to help, the post breaker often trips when the microwave or other appliance is used.. Any thoughts about connecting a separate power cord from the park 15 amp pedestal outlet/breaker then routing it into the trailer to power the electric space heater??? had to ask

We just turn off the space heater when running the microwave or electric skillet. It's usually only a few minutes so no big deal.

A 30amp should provide 3600w for short bursts but only about 3000w continuously. A space heater will typically be around 1500w. If the water heater is running (another 1500w) and a 250w fridge (on electric)...you are pushing the outlet to the limit, lights, fans, TV and other small loads can easily push you over the 3600w and pop the breaker.

As mentioned, run the fridge and water heater on propane will keep the power draw down and then shut off the space heater while using other high draw items.

Running a line to a separate pedestal will work but as mentioned, many campground operators won't be happy. Particularly if electricity is included in the site cost.

As to what CharlesinGA says about campground restrictions—campgrounds are all about the money. If you find one that restricts outlet usage, you could ask to be allow to use more than one if you are willing to offer to pay an additional charge for electricity. Also, sometimes it is easier to ask for forgiveness than for permission!

I have been doing this for about 15 years without any issues. I just run the cord thru a slide out seal. I have never been questioned by any campground person. As mentioned by time2roll be sure to use a heavy duty extension cord.

I have been thinking the same thing for my class C. Then I saw This post and it does seem doable.

But my thought would be to use One of These they come in different lengths and I could put it where I wanted it.

HW, MW and space heater are high draw appliances. The refer and charger also contribute so keep the usage down. I added a separate circuit for 30A pedestals that can be plugged into the 20A pedestal plug when desired.

First put your water and fridge to propane only.

If you must run a separate cord to pull in more power.... use an extension with #12 wire (no 18, 16, 14)

Be aware that some campgrounds, especially private ones, will not allow you to use more than one receptacle on the post at one time. Read their rules carefully. Sometimes it has to do with electric consumption and cost, other times it has to do with overloading the system. Some won't care, some will.

That would work.
