Ok your testing somewhat eliminates the loose wire/bad splice. You said no problems when hooked to shore. So let's test the gennie without the ATS in place . Wire the gen leads to the input leads going into the coach. What happens?

So remove shore from ATS and replace with gen leads?. OR
Disconnect load lines to coach at Switch and hook gen leads direct to them?

Ok did that and Volts dropped —- Blk 45.7 and red 46.3
Both direct to load lines to coach.

No! connect the white and red, then white and black! each should have 120 volts AC.
Previous test does not eliminate possibility of a bad wire!
Make sure it is her new hair dryer!

Did you put any load on it?
If you did then it sounds like a bad wire between genset and transfer switch.

Envlethen- WHAT? How can it be bad wire if I tested and both made white hot by attaching white to red then white to black?

At what location?
I suggested doing it at the junction box at the genset.

That’s where I hooked up wires and went to output to get reading before ATS. Neutral showed 120 with both red and blk.

Disconnect load lines at ATS and connect directly to lines from generator thereby bypassing the ATS altogether. Assuming voltage is 120, then turn on air conditioning in the coach. Measure voltage again. Easier than customizing the frau's hairdryer but is essentially the same test
