Possible electrical damage - new to RVing

I have wonderful news to report.... I installed a new power converter - same model...same brand - and checking the generator - disconnected from the rest of the power grid of the camper... the generator checked out good ..! and after installing a new transfer switch assembly ..which the old one was toast... lots of arcing damage - I fired the generator up - and after the wait period of approximately 2 minutes .. the power came on...and everything was ok. The TVs are good, the microwave is good. The refrigerator is good. the heating and AC system is good.. the slide out motor is good... the awning motor is good... the only thing NOT working are two overhead lights which I have not checked out yet. I was relieved. The camper has been at the park since the problem occurred and the park owner was with me when we fired it up. I think he was rather relieved also as he said he would pay for anything that was damaged. He is a good guy. The RV park is near Lake Murray in South Carolina. He told me that if anything died over the next year ... he would still replace it. I thought that was quite generous. I did purchase a Campo Line tester for future hookups... and will plan to buy any other type of electrical protection I can. SO.. in the end .. I learned a helluva lesson and thanks for all the replies and helpful advice.
