New Rockwood 2910 TS AC not cooling enough
I just purchased a new Rockwood 2910 TS with the upgraded 15,000 BTU AC unit (standard was 13,500). On my first trip out it wasn't cooling well and the dealer checked it and replaced the unit. On my ...

In humid parts of Texas (Oklahoma, Arkansas, Louisiana, Mississippi, etc) in a RV that size, particularly a "lightweight" with thinner walls and single glass, one A/C unit, even a 15,000, will not keep the unit as cool in full sunlight as many people accustomed to climate control would like it to be. The loads, heat from sunlight and heat of evaporation of the water, are just too great for the available cooling power.
Same capacity works fine in those places where heat loads are less. A box parked in the woods in northern Minnesota or on the Northwest coast might get away with 6000 BTU/HR but take the same rig to San Antonio in August and you might need 40,000. Installing 13,500 to 15,000, or 30,000 in two units, is a compromise between cooling needed and practicality of powering the A/C from a campground post. Definitely also a matter of economics, you target an "average" climate rather than try to make everybody buying a RV pay for suitability to "worst case" conditions.
Second A/C, 13.5 or 15, maybe even 8K (which will power from a 15A circuit) might be enough to get you where you want to be, or maybe not. Depends on whether you are trying for low 80s, mid 70s, or mid 60s like inside a Texas shopping mall.
