How much AC is needed?

I should have mentioned that the trailer manufacturer (Grand Design) claims that the trailer is well insulated. They state that it has R-40 in the roof, R-11 in the floor and R-9 in the walls in their brochure. The manufacturer also claims that the 15K BTU AC unit should work just fine and they have not gotten any complaints.

As for adding a second AC unit I was just curious and I was mainly interested in the actual AC unit install on the roof itself and all that goes with that, like sealing the roof and securing the AC unit its self. I wasn't that worried about the electrical aspect of the install and I don't mean to minimize that aspect of the install, its just that I'm an engineer and I've worked with electricity (AC and DC) my entire career, so I'm sure I could figure that out. All that said, I honestly don't think I'd ever do it. Seems rather crazy to plan on adding a second AC unit to brand new trailer. It would make more sense just to buy another trailer if the 15K BTU unit can't do the job.

You mentioned camping in summer in Texas and Florida. Not sure about Texas, but summer camping in Florida is hot and I'm very glad I had the dealer install the bedroom AC. It is most likely already wired for the AC. They offer two versions, one controlled by a thermostat which is more expensive, and one that just has the controls on the panel - no auto on/off.
