Generator size

We have been looking at used Class A coaches and it got me thinking (very rare for me) about generator capacity and/or capability.

Many of the coaches have a 5000 watt generator and some have 5500 up to 7500. It only makes sense that the larger ones have more capacity but my question runs to actual manufacturer or industry specs. Will the smaller (5K or less) units run the coach appliances well enough or were there a lot of them put out with under capacity gennies? I know this depends upon what the coach has, appliance-wise, but, in general, were most coaches made with enough gen capacity or are there a lot out there with under-powered gens?

I have been asking a lot of questions and will probably have many more but it looks like we are going to be seriously looking at used (older) coaches as the year unfolds.

Thanks gang.

Haven't seen 5.0, but there's a lot of 5.5KW out there, in the 30amp coaches. These are 45amp units, so has at least 15amps more available than the shore power. It accomplishes this by providing a separate 20amp feeder breaker on the genset itself, for the rear ac.
They only get larger from there and even with our 50amp coach, the 7.5KW quiet diesel gen. will run all that's necessary and even though a 10KW is closer to the industry standard now. Others have much larger units and especially with the all electrics out there, these days.
