15,000 air conditioner

Ours does well. Changed to digital thermostat and keep the filters clean.
In 90+ temps with 90+ humidity, we augment with fans. No issues.

Bigger is better in this scenario. Went with 2 and have never looked back.

Every jayco fifth wheel I've looked at has an analog thermostat, units with msrp of close to $70,000.

It never ceases to amaze me that jayco insists on putting the cheap non working analogs in when a digital would cost very little in addition.
