NPS has been very cooperative in trying to solve the problem.

We installed this months ago. Still running into the usual issues when it's hot out.

We have better luck if the side cover for the generator is left off while driving. Shouldn't have to do that, though.

Would rather have an Onan.

Due to the extreme heat wave, I was able to test the new wiring harness. At 100 degrees plus in Thousand Oaks, CA I ran both generators for an hour with no problems.
