We had a similar problem in our Allure. I mostly noticed it with the ac running on the gen side, ac would run then cycle off. I actually forget the exact symptoms but I traced it to a bad transfer switch. The contacts or the actual relay that pulls in the contacts on the gen side were worn out. Replaced the transfer switch with a new voltage sensing and surge protecting switch and all is good.
Not to say a breaker didn't trip on gen either. That has also happened when camping at a horse show and the girls were making coffee, toast and had griddle on at same time. Took a minute to figure that one out.
