Changing 13.5 BTU A/C to 15?

I'm still poking around some newer used buses, with the though the 3 a/c units is a must have.

I found what looks like a good buy, has three units but they are 13.5.

What's the general thought on "if they aren't cold enough, swap em for new 15 btu units"?

I think you will find that three 13k btu units will be fine. My experience with a fiver that I never got cold enough in North Carolina summers was with a 13k in the front/bed room, and a 15k in the living room. This all had to do with the type and amount of insulation the fiver had from the factory (Heartland). I just traded it in for a previously owned Providence 42p DP. So far the wife and I are very pleased with the performance of the three 13K units it came with from the factory. The only change I would want is the ability to run them in motion without the generator. But I don't think there is an inverter setup available that would handle the load. One extra gallon of fuel per hour is not an unreasonable trade off. Bottom line is, I love the way it is, I'm sure you'd be completely satisfied with the three 13K units. The extra help from the chassis A/C unit makes up the difference when in motion.
