fotofx is right -- size is just one variable.
Assuming you're in Alabama and want to camp in summer, there is little doubt in my mind that a 36-foot trailer should have 2 air conditioners (of roof-top type limited to no more than 15,000 BTU/hr capacity per unit).
Some central air conditioners are much larger but since you didn't mention that, I'll assume you have a 15k roof-top A/C.
In my opinion any RV much larger than 25 feet could use more than a 15K A/C in the south during summer. Some 27~30 foot RVs get by with one air conditioner, but they have to be much more diligent at reducing heat load.
