Adding AC to 3150

We are thinking about adding a second AC unit to our Tracer 3150, putting it in the bunkhouse. We live in Texas and unless it is winter (which is scheduled for a Tuesday in February most years), it is murder hot when we get to the campground. A friend who had a similar bunkhouse said he added one and ran a wire molding to the back wall and had a 15 amp inlet (like this one: that he plugged in with an extension cord. Most places I go have a 15 amp plug. I'm seeing ac units that run 13 amps. Anyone done this? Seems a lot less hassle than switching out to run 50 amp. Seems a good use of the bunkhouse vent, which I don't use, but have to keep a vent pillow in to keep the boys asleep past sunrise.

Any thoughts? I've seen a 3150 with a second unit but it didn't belong to the person who was camping in it (borrowed from a brother-in-law) so they didn't know anything. Any reason not to do it?

You need to use 20 amp wiring and thru wall plug.
Most camp grounds have a 20 amp plug in.

Most a/c unit take up to 19 amps to start then run at about 14 amps.

I'd want to know the framing was there around the vent to support the ac.

Framing shouldn't be too much of an issue. Some that have done it, just add blocking if necessary once the vent is removed. Otherwise, don't we all walk on the roof to clean and inspect? And I'd bet none of us are even close to the 100 lb max weight of an AC.

At least in Heaven, RVs will be perfect, and I won't have to keep fixing them.
