Will getting a larger roof A/C solve the problem?

I have a 1993 Winnebago Brave 27RC and it has a coleman roof A/C. The BTU's are about 12,500. If I install a 15,000 Coleman roof A/C will it stay cool better in the hot Florida summer afternoon?

Not really. The heat load is the big culprit, and 2,500 more BTU's will do very little. Ask yourself, how much cooling would I get from a 2,500 BTU air conditioner? Would a unit that size cool down my RV just a little? However much a unit that size would cool down your RV, that is how much effect the 15000 unit will have.

Save your money and invest in other strategies such as window tinting, extra insulation, or even a portable air conditioning unit.
