Thanks so much for the information. We have a 2016 33.5 Miramar and new to motor coaches but not camping as we traded in our HitchHiker 5th wheel recently. The previous posts really helped in zeroing in on the possible reason for the popping sound we heard today and localized to the back bay at the transfer switch. Based on the posts, we think we have avoided any long term damage and will pursue having the transfer switch checked and possibly rewired. Happy motoring y'all!
